298 MR. BELL, HORiE CARCINOLOGIC^ ; 



British Museum. It has a prima facie resemblance to a yoving M. carinata, but diEFers 

 from that species ia its proportions, in the arrangement of the granules, in the hairy 

 line on the anterior margin, and hi the ultimate and penviltimate joLats of the posterior 

 feet being ciliated. 



Myra mammillaeis, mihi (Tab. XXXII. fig. 5). Testa ovata, glabra, tuberculis parvis 



elevatis sparsim instructa ; dentibus posticis brevissimis, rotundatis. 

 Hab. ad oras Australiae. Muss. Brit., Bell. 



Carapace oval, somewhat produced before and behiud, the surface polished, and studded 

 with numerous small distinct globular tubercles, which also form a Hne along the 

 middle of the back, around the margin, on the hepatic region, and on the pterygostomian 

 crest. Front somewhat waved, slightly emarginate, a smaU 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 Hnes 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, sulcated 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 prima facie relation to JPerse- 

 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. 



3f}/ra variegata of Ptiippell (Krabben des Eoth. Meeres, p. 17. t. 4. f. 4) is not a Myra, 

 but is probably a young individual of a species of Philyra. 



Genus Mtuodes, BeU. 



Char. Gen. — Testa ovata, rostro emarginato terminata, postice dentibus tribus, quaruni media longior, 

 armata. Orbita fissuris tribus, brevibus. Fossa antennaria fere longitudinales. Pedipalpi externi 

 caule exteriore subcurvo, baud dilatato. Pedes antici testa vix longiores ; manibus pyriformibus, 

 baud longioribus quam latioribus ; digitis tenuibus valde elongatis, curvis, apice aduncis. Abdomen 

 Maris triangulare, segmentis tertio ad sextum coalitis, — Fcemin^ ? 



Tliis genus, which is nearly allied to Myra, difi"ers from it in the foUowing particulars. 

 The antennary fossae are less oblique in their dh'ection, 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 pecidiarity 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 Ave except the fingers. The hand especially, which in Myra is always many 

 times longer than it is broad (in M.fugax <S not less than seven times), is in My r odes as
