REPORT ON THE ANOMITRA. 11 



The clielipedes arc pubescent and of moderate length, the propodal joint (including its 

 finger) is not twice the length of the carpus. The meral joint is trigonal, and the lower 

 edge ends in a rounded tubercle. The carpus is armed with two obtuse teeth on its 

 anterior edge (of which the superior is larger), and a somewhat conical process on the 

 upper border. The propodus bears two rounded tubercles on its outer surface, near the 

 attachment of the dactylus, and the upper border is produced into a lobe-like process 

 which is directed inwards. The opposed fingers have their edges smooth, and the 

 dactylus is remarkably broad and compressed, its outer surftxce being slightly concave, 

 the inner convex ; both fingers are dentate, the upper fitting into the lower, and a few 

 stifi" yellow hairs are also present. The first two pairs of ambulatory limbs are of con- 

 siderable length, and in addition to the usual short pubescence they are sparingly clothed 

 with long club-shaped hairs ; the dactyli exceed the propodi and carpi in length, and 

 terminate in a curved yellow claw. The third pair have the merus slightly longer than 

 the carpus, and the propodus bears a short horny claw which is opposed to the dactylus. 

 The fourth pair are of considerable length and folded over the carapace, the basal joint is 

 large, and its attachment to the second joint is strengthened by a small calcareous process 

 which passes between the two ; the merus is about one and a half times as long as the 

 carpus, and the propodus bears a horny claw on either side of the dactylus, the latter, 

 however, exceeding these in length. Both the third and fourth pairs possess club-shaped 

 hairs on their borders. 



The abdominal segments in the female are broad and pubescent, with a median 

 rounded elevation on the outer surface, and the edges fringed with long hairs. The 

 abdominal appendages are well developed (except the first pair, which are rudimentary), 

 each terminating in a lamellar outer portion and a cylindrical and shorter internal branch. 

 The openings of the oviducts are remarkably large. The sternal sulci pass forwards as 

 far as the segment which bears the second pair of legs (first pair of ambulatory legs), but 

 they do not end in tubercles, their terminations are, however, separated by a slight 

 median elevation. 



Breadth of carapace (of the larger specimen), 12 mm. ; length of carapace ir5 mm., 

 of chelipede 15 mm., of first ambulatory limb 16 '5 mm. 



The orbital fissure, the form of the dactylus of the chelipedes, and of the last pair of 

 legs, are the distinguishing characters of this species. The arrangement of the sternal 

 sulci in the female is particularly noteworthy, showing in this respect an apparent 

 connecting link between Stimpson's genera Cryptodromia and Dromidia, 



Habitat. — Station 163a, off Twofold Bay, Australia; depth, 120 fathoms; bottom, 

 green mud. Two female specimens were obtained ; one of these is protected by an 

 Ascidian.
