Aglaophenia rhynchocarpa Allman, 1877

(figs 1K, 8G–I)

Aglaophenia rhynchocarpa Allman, 1877: 40, pl. 23 figs 5–8.― Vervoort, 1968: 73, fig. 34.― Calder, 1997: 59, fig. 18.

Material examined. Stn.8: 0 5.12.2009, 17 m—numerous cormoids to 4 cm high, some bearing corbulae, on unidentified substrate (parts as MHNG-INVE-68734 and MNHN-IK.2009-811).

Remarks. For synonymy and a description of its trophosome, see Calder (1997). The corbula has been briefly, though correctly described and illustrated by both Jäderholm (1903, as Aglaophenia cylindrata Versluys, 1899) and Vervoort (1968), while the accounts and figures provided by Allman (1877) and Nutting (1900, as A. rathbuni) are misleading. Ideally, its highly complex structure should be thoroughly described based on images obtained by scanning electron microscopy. Figure 8I shows a lateral view of the corbula.

Caribbean records. Los Testigos (Versluys 1899, as A. cylindrata), Anguilla (Jäderholm 1903, as A. cylindrata), Tortugas (Wallace 1909), off Barbados (Nutting 1919), Puerto Rico (Fraser 1944), Virgin islands (Vervoort 1968).

World distribution. Florida (Allman 1877, Nutting 1900), off La Havana (Nutting 1900; Fraser 1944), Brazil (Nutting 1900, Vervoort 1946, both as A. rathbuni), Sierra Leone (Vervoort 1959, pro parte, as A. latecarinata Allman, 1877), Bermuda (Ritchie 1909, Bennitt 1922, both as A. cylindrata; Calder 1997), Colombia (Flórez González 1983).
