298 MR. BELL, HORZ CARCINOLOGICE ; 
British Museum. It has a primé facie resemblance to a young M. carinata, but differs 
from that species in its proportions, in the arrangement of the granules, in the hairy 
line on the anterior margin, and in the ultimate and penultimate joints of the posterior 
feet being ciliated. 
Myra MAMMILLARIS, mihi (Tas. XX XII. fig. 5). Testà ovatä, glabrá, tuberculis parvis 
elevatis sparsim instructä; dentibus posticis brevissimis, rotundatis. 
Hab. ad oras Australie. Muss. Brit., Bell. : 
Carapace oval, somewhat produced before and behind, the surface polished, and studded 
with numerous small distinct globular tubercles, which also form a line along the 
middle of the back, around the margin, on the hepatic region, and on the pterygostomian 
crest. Front somewhat waved, slightly emarginate, a small tooth over the inner canthus 
of the orbit. The teeth on the posterior part rounded, not longer than broad, the lateral 
ones compressed. External foot-jaws tuberculated on the anterior portion, the palp some- 
what dilated outwards. Sternum with lines of minute tubercles anteriorly. First pair 
of legs in the male twice the length of the carapace, stouter than in the other species of 
the genus; the arm covered with depressed tubercles; a scabrous line on the inner mar- 
gin of the wrist, and on the outer and inner edge of the hand ; the fingers half the length 
of the hand, suleated and scabrous. The remaining legs filiform, slender, the surface 
punctated, the terminal joint awl-shaped, sulcated. 
Length of carapace 2 in. 
Of this fine species there are several specimens in the British Museum and in my own 
collection. It was brought from South Australia. Its primá facie relation to Perse- ' 
phona is striking, but it differs from that genus in the essential generic characters, par- 
ticularly in the form of the hand, and of the palp of the external foot-jaws. | 
Myra variegata of Rüppell (Krabben des Roth. Meeres, p. 17. t. 4. f. 4) is not a Myra, ` 
but is probably a young individual of a species of Philyra.

This genus, which is nearly allied to Myra, differs from it in the following particulars. 
The antennary fossæ are less oblique in their direction, being so placed that the anten- 
nules lie nearly longitudinally.. The palp of the external foot-jaws is merely curved on its 
outer edge, instead of being first dilated and then distinctly narrowed towards the apex, 
as in Myra. But the most remarkable peculiarity is in the form and length of the ante-- 
rior legs, which in Myra are almost filiform, and, even in the female, more than twice as 
long as the carapace; whilst in the present genus they are not longer than that part, if in 
both Cases we except the fingers. The hand especially, which in Myra is always many 
times longer than it is broad (in M. fugax & not less than seven times), is in Myrodes as
