Paralomis inca Haig, 1974: 157 , figs 3, 4.

TYPE LOCALITY. — Pacific coast of Ecuador and Peru, 06°31.5’S, 81°01.5’W, 600- 800 m.

MATERIAL EXAMINED. — 6 ♀♀ (CL> 90 mm). Informa-

tion about smaller size classes comes from the original description ( Haig 1974).

SPECIMEN FIGURED. — 7°49’00’’S, 80°38’00’’W, 705- 735 m, 1 ♀ CL 96 mm ( USNM- 259223).

REMARKS

No specimen of Paralomis inca ( Fig. 5 ) examined by us was smaller than CL 90 mm, and the smallest of the “adult” type collection ( Haig 1974) was CL 80 mm. In the original description ( Haig 1974: fig. 4), a figure of a juvenile (CL 69 mm) is double the normal minimum size of maturity for many species of the genus ( Zaklan 2002). Haig (1974) does indicate a marked difference between juvenile and adult spines ( Fig. 5 ). In large specimens, tubercles are low, regular mounds, with a circular patch of short setae at the apex. In the small paratype, the dorsal ornamentation is much more spiniform, with long setae emanating from the apex.
