HETEROFRAGILIA FIMBRIATA Hedgpeth 
FiGcurE 47 
Heterofragilia fimbriata HrepGprrty, 1943b, pp. 53-54, pl. 10, figs. a-7. 
Another curious pycnogonid from near Martinique (476 fathoms) 
whose nearest relative appears to be the East Indian Pycnofragilia 
hamisetosa (Loman).”* In some respects it also resembles Cilunculus 
Loman (1908) but does not have the well-developed propodus 
characteristic of that genus. Cilunculus was originally reported 
from the East Indies and Japan, but it is also a Western Hemisphere 
genus, since Mello-Leitéo’s Acanthammothella pennai (1946) from 
Brazil is obviously a Cilunculus. 
Both of these aberrant genera from Martinique are known from 
Ficure 46.—Ephyrogymna circularis Hedgpeth: a, Dorsal view of holotype (proboscis fore- 
shortened); b, ventral view of chela; c, terminal joints of palpus; d, leg; e, tarsal joints; 
f, oviger; g, anterior view of eye tubercle.
