Mr. G. Hodge on the British Pyenogonoidea. 115 
rostrum,—Zetes being much elongated and seated upon a sort 
of stalk, Achelia being short and stout. 
I have three species of this genus to describe, for which the 
specific names of echinata, hispida, and levis are proposed. 
Achelia echinata (Hodge). Pl. XII. figs. 7-10. 
Animal robust, with moderately long legs, furnished with strong 
spines produced from little eminences upon the limbs and 
body. The oculiferous tubercle is directed forwards, and ter- 
minates in a little pot directed backwards. Inner palpi of 
the same length as the oculiferous tubercle ; the outer longer 
than the rostrum. Colour fine sienna to a pale straw. 
This species has been found at the Channel Islands, the Isle 
of Man, and upon the Durham coast. It is by no means un- 
common from low tide to a few fathoms. Length ,2, of an 
inch. 
Achelia hispida (Hodge). PI. XIII. fig. 11. 
Animal robust, hairy. Limbs long, first four jomts much stouter 
than the others. Thorax much produced in front. Inner 
palpi large and stout, with a circlet of little spines at the 
base and at the top of the first joint ; outer palpi longer than 
the rostrum. Oculiferous tubercle scarcely reaching beyond 
the origin of the inner palpi. 
Several specimens from Polperro. Length +8; of an inch. 
Achelia levis (Hodge). Pl. XIII. fig. 12. 
Animal robust. Limbs smooth and regular in form, with a few 
small hairs scattered over them, principally on the femoral 
and tarsal joints. Inner palpi rather long, slender; outer 
palpi as long as the rostrum. Oculiferous tubercle small, 
produced considerably behind the inner palpi. 
Several specimens from Polperro. Length +3, of an inch. 
Phoxichilidium virescens (Hodge). Pl. XIII. figs. 13-15. 
Rostrum stout, slightly thickened in the middle, truncate at the 
apex. Footjaws slender, and closely approximated at their 
origin, each finger with 6-8 teeth. Legs moderately long. 
Colour pea-green. 
Several specimens from Polperro. Length +3, of an inch. 
This species might at first sight be mistaken for Phowichi- 
lidium olivaceum (Gosse) ; but the closely approximated footjaws 
at once show its distinct character. .
