Family ENDEIDAE Norman, 1908 
This family is characterized by the absence of chelifores and palpi, 
and the presence of ovigers only in the male. The ovigers are 7- 
jointed. The legs are long, terminating in a well-developed propodus 
with auxiliary claws. The only known genus is Endeis.

Endeis Norman, 1908, pp. 231—-233.—Co.z, 1910, p. 194—Catman, 1915a, pp.

The unhappy history of this generic name is marked by several 
impassioned polemics and much spilling of ink (see Pallenidae). As 
can be seen from the incomplete synonymy given below for Endeis 
spinosa, the matter is still unsettled. This is unfortunate in view of 
the wide distribution and ecological interest of this species. It seems 
too much to hope that future specialists will agree on the matter. 
Marcus is the first to notice that the name Endeis requires feminine 
endings for its species. 
Endeis is represented in the northwestern Atlantic by one species, 
E.. spinosa, but imasmuch as EF. charybdaea has been found on the 
coast of Brazil, it may also be expected in the Caribbean. The only 
reliable character on which both sexes of the two species may be 
separated is the larger size of EL. charybdaea; the length of the body, 
exclusive of the proboscis, is 8-10 mm., whereas the body of EF. spinosa 
is never more than 6.5 mm. in length and is usually less. At best 
this is an empirical distinction, and FE. charybdaea seems to be an 
uncertain species.
