scribing it as 5-jointed; there are six articulated joints and a segmenta- 
tion near the base of the third joimt. As generic characters, dis- 
tinguishing Halosoma from Phozichilidium, Cole (loc. cit.) mentions 
the compact body with the last pair of lateral processes slightly separ- 
ated from the preceding pair and the intermediate development of 
the neck (between Phozichilidium and Anoplodactylus). The position 
of the lateral processes is somewhat variable in the genotype, however, 
and in a few specimens the body is completely circular. The femoral 
cement gland of Halosoma viridintestinale is of particular interest 
(fig. 25, 6). Viewed from directly above, it appears to be a circular 
opening at about the middle of the dorsal surface of the femur. From 
the side, however, it is a very short tubular process. The walls of the 
tube are transparent and cannot be easily demonstrated. Genital 
protuberances occur on the last two pair of coxae in the genotype, 
about a third as long as the width of the joint, rounded.

RECORD OF COLLECTIONS 
Loggerhead Key, Tortugas, Fla., from algae and old coral rock, 4 feet, July 14, 
1926, C. R. Shoemaker coll., 1 specimen (female). 
This single female specimen appears to be Halosoma because of the 
slightly developed neck and narrowly separated lateral processes. 
The forward end of the cephalic segment is raised, and there are long 
spines on the tibiae as in H. robustum. Identification of an isolated 
female in this family is subject to reservation, however, and further 
collections may prove this to be another species, possibly Phozichili- 
dium virescens Hodge.

Chelifores 2-jointed, with small chelae. Palpi lacking, but females 
in many species with peculiar processes on ventral surface of proboscis. 
Oviger usually 6-jomted (nine in A. spinosus Mobius). Auxiliary 
claws reduced or minute. Males with conspicuous femoral cement 
glands, of various types. 
Although Wilson (1880) suggested that his Anoplodactylus might 
be congeneric with Anaphia Say, he preferred to retain Anoplodactylus 
until specimens from South Carolina, the type locality of Say’s
