XXI PHOXICHILIDHDAE—PYCNOGONIDAE 539 
referred to Phowichilidium. A. neglectus, Hoek, comes from 
1600 fathoms off the Crozets. Oomerus stigmatophorus, Hesse 
(1874), from Brest, seems to belong to one or other genus, but 
is unrecognisable. Anaphia, Say (1821), is in all probability 
identical with Anoplodactylus, and if so the name should have 
priority. Halosoma, Cole (1904), is an allied genus from 
California. 
A 
Fira. 287.—Anoplodactylus petiolatus, Kr,., Britain. A, Dorsal view; B, side view. 
Fam. 9. Phoxichilidae.'— Appendave I. and II. absent; 
appendage III. present only in the males, 7-jointed, with minute 
scattered spines; auxiliary claws well-developed ; body and legs 
slender. The only genus is Phowxichilus (auctt., non Latreille, 
Chilophozus, Stebbing, 1902); the type is P. spinosus, Mont. 
(non Quatrefages), from the N. Atlantic, and P. vulgaris, Dohrn, 
P. charybdaeus, Dohrn, and P. laevis, Grube, are all very similar. 
Endeis gracilis, Philippi (1843), is probably identical with 
P. spinosus, or one of its close allies. There are also known 
P. meridionalis, Bohm, P. mollis, Carp., and P. procerus, Loman, 
from the East Indies; P. australis, Hodgson, from the Antarctic ; 
P. béhmiw, Schimk., of unknown locality; and forms ascribed to 
P. charybdaeus by Haswell and by Schimkewitsch from Australia 
and Brazil. 
Fam. 10. Pycnogonidae.— Appendages I. and II. absent ; 
appendage III. present only in the male, 9-jointed, with small, 
simple spines; auxiliary claws absent or rudimentary ; body and 
legs short, thick-set. 
The only genus is Pyenogonum, Briinnich (1764) (Polygonopus,
