144, Mr. H. W. Bates on the Longicorn Coleoptera 
at the tips of short stout pedicels. The head-lobes are small, 
white, and pectinate. The foot is very small and narrow. Un- 
fortunately, owing to a gale suddenly springing up and cap- 
sizing my arrangements, I was unable to note any peculiarities 
of the neck-lappets and lateral filaments. 
Glyphis quadriradiata, Sow. 
An examination of the animals of P. P. Carpenter’s group of 
Fissurellids, which he has appropriately named Glyphis, on ac- 
count of their beautiful sculpture, is the more important as they 
cannot from their shells alone be distinguished from Lucapina 
of Gray, with which, in our ‘Genera,’ my brother and myself 
have associated them. 
The animal of this species is semiopake, milk-white. Tenta- 
cles moderate; eyes large and black, on prominent tubercles at 
their outer bases. Muzzle short and rounded. Mantle double- 
edged, the outer or upper margin simple and plain, and just 
turned over the edge of the shell, the lower forming an expanded 
membranous curtain, fissured in front, extending considerably 
beyond the shell, and overhanging the foot ; the margin plain, 
simple. Sides with a row of short, opake-white, conical papille 
(nine on each side). Foot ovate, moderate, rather acuminate 
behind. The species occurs in Japan; but my living animal 
was dredged from 29 fathoms, stones and shingle, in a tide-race 
at the extreme point of the Regent’s Sword.

Genus SrRIPHvs, nov. gen. 
Body oblong-ovate, convex, setose. [Forehead and muzzle 
short, as in the Leiopodine generally. Antenne elongated, 
hair-like, setose both above and beneath. Thorax convex ; lateral 
spines tuberculiform, and placed behind the middle. Elytra 
free from tubercles and ridges, obtusely truncated. Legs mode- 
rate; thighs clavate; basal joint of hind tarsi about equal to 
the two following taken together. 
3 Apical ventral segment obtusely rounded; dorsal sere 
truncated, with the angles distinct. 
2 unknown. 
The species which constitutes this genus would probably be 
better placed in a section or subgenus of Sporetus. It differs 
greatly from the Sporefz im colour, beg of a rich changeable 
silky-green hue.
