Type material. LECTOTYPE, female, 11.2 mm, ovigerous (40 eggs), AM G5417; 3   PARALECTOTYPES, female, AM P 37181 View Materials ; Port Jackson , New South Wales, Australia, [approx. 33°51'S 151°16'E] GoogleMaps   .

Springthorpe & Lowry (1994:5) have discussed the general problem of Haswell “types”. For Amaryllis brevicornis   , two lots of material in the Australian Museum collection ( AM G 5417 and P 3440) were regarded as syntypes. The first lot ( G 5417) was registered into the collection and labelled as “Type” by A. R. McCulloch in 1905; the material is from Port Jackson (the type locality and the only locality recorded for this species in Haswell’s original publication of 1879). The second lot ( P 3440), was registered into the collection in 1912 and was not then regarded as type material. It is also from Port Jackson. However, the register entries for P 3439 and P 3441 are also A. brevicornis   , from Griffiths Point and Port Stephens. This set of localities—Port Jackson, Port Stephens and Griffiths Point—are the three localities given by Haswell (1882) in his subsequent report of A. brevicornis   material. It seems to us that the material of AM P 3440 should not be regarded as type material.

The syntypes   of A. brevicornis   were mounted with glue onto a glass plate and stored in alcohol for more than 100 years. The specimens were heavily coated with precipitate from the preserving fluid. We have removed one specimen from the glass plate, peeled off the glue, and removed as much as possible of the accumulated deposit. However, many setae (for which insertion points can still be recognized) have been lost and some parts are still not clearly visible. Although we are designating this specimen as a lectotype   , we have chosen to describe and illustrate in detail a female not from the type collection. The specimen described (from Clovelly Pool, AM P 37116 View Materials , just south of Port Jackson ) agrees extremely well with all characters that can be determined from the lectotype   .

One specimen from the original syntype series of 5 specimens is not A. brevicornis   . It has a serrate epimeron 3 and is a specimen of A. keablei   . It is now registered as AM P 37180 View Materials .

Description. Based on female, 11.0 mm, AM P37116 View Materials . Head much deeper than long, anterior margin with notch extended into a slit; rostrum absent; eye present, elongate, reniform. Antenna 1 peduncular article 1 not ball-shaped proximally, distal margin with small medial spine; peduncular article 2 medium length; flagellum with or without callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1, without calceoli. Mouthpart bundle subconical. Epistome/upper lip almost straight (lateral view). Mandible lacinia mobilis a stemmed, distally-cusped blade; accessory setal row with intermediate setae; palp article 2 with 2 posterodistal setae, article 3 without A3-seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus shorter than propodus (0.8×); propodus, posterior margin without robust setae. Gnathopod 2 palm slightly   acute, with 1–3 lateral robust setae, 1 medial robust seta. Pereopods 3 and 4 merus and carpus without setal fringe. Pereopod 4 coxa with anterior and posterior margins subparallel, anteroventral corner rounded. Pereopods 5–7 with distal articles elongate, dactyls short and stocky. Pereopod 5 basis expanded posteriorly, rounded. Pereopod 7 basis rounded posteriorly, posteroventral corner rounded, posteroventral margin straight.

Epimeron 3 posterior margin smooth, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 8 robust setae; outer ramus without large spines between robust setae. Uropod 2 inner ramus slightly   constricted. Uropod 3 rami lanceolate; without plumose setae; outer ramus 1-articulate. Telson moderately cleft   (about 40%).

represent 0.05 mm; remainder represent 0.1 mm.

Variation. Amaryllis brevicornis   , as we regard it here, shows more variation in the robust setae of gnathopod 2 palm than does any other species of Amaryllis   . Adult females can be found with from 1 to 4 lateral (but always 1 medial) robust setae on the palm. There is also some variation in the arrangement of robust setae on the outer ramus of uropod 1. In some specimens, instead of regular spacing of the setae there is a distinct gap between the 1 or 2 proximal robust setae and the 1 or 2 distal robust setae. The variation in these characters does not occur consistently with either size or geographical distribution, with any other character, or with each other. (A similar gap in the uropod 1 robust setae also occurs in A. migo   , but in this case it consistently appears with other species characters.)

Remarks. Amaryllis brevicornis   belongs to the group of species with a smooth posterior margin on epimeron 3 and a rounded posteroventral corner on the basis of pereopod 7. Within this group it is most similar to A. kamata   , from which it differs in the shape of the epistome and the length of the gnathopod 1 carpus.

Habitat. Amaryllis brevicornis   has been often collected with sponges; less often with other sessile invertebrates such as bryozoans, hydroids and ascidians, or in algal holdfasts, coralline algae and coarse rubble.

Distribution. Coastal New South Wales, southeastern Australia; to 24 m depth.
