REPOET ON THE ANOMURA, 59 



third left leg has the propodus dilated, with its outer surface faintly granular and a well- 

 marked series of granules on the lower border, which is sharp ; the dactylus is about one 

 and a half times the length of the penultimate joint, with its outer surface longitudinally 

 canaliculate, the l^orders are faintly granular, and fringed with hair-like setae which 

 become yellow and horny towards the apex. 



The penultimate abdominal segment bears a T-shaped marking ; the terminal segment 

 is irregular in shape, with a sinuous margin. 



Length of body 24 mm., of left chelipede IG mm., of right chelipede 13 mm., of third 

 left leg 22'5 mm., of ocular peduncle 5 mm. 



Pagurus dearmatus is allied to Pagurus deformis' Milne-Edwards, and Pagurus 

 pedunculatus (Herbst) ; it comes nearest to the latter, in which, however, the propodus of 

 the left chelipede is both tubercular and granular on the outer surface. From Pagiirus 

 deformis it is distinguished by the form of the penultimate joint of the third left leg, 

 which in that species is cariuated on the outer surface. 



Habitat. — Admiralty Islands, 16 to 25 fathoms. A female with ova, in a shell of 

 Stromhus variabilis, Sow. 



Pagurus similimanus, n. sp. (PI. VI. fig. 6). 



Characters. — The anterior portion of the carapace is six-sided, the front with a well- 

 marked projection external to the insertion of each ocular peduncle, the surface is smooth 

 towards the middle and bounded by a Y-shaped line posteriorly; a few long hairs arranged 

 in tufts are present towards the lateral margins ; the posterior portion is entirely 

 membranous. 



The ocular peduncles are of large size and shaped as in Pagurus deformis, ]\Iilne- 

 Edwards, constricted towards the middle, with the cornese dilated and not deeply 

 pigmented, and their outline semilunar when seen from above; a dark band runs along the 

 inner and outer surfaces of each peduncle ; the ophthalmic scales are broad at the base, 

 their apices with three spines each and several long hairs. The antennal peduncles 

 extend almost to the end of the eye-stalks, while the joints are broad and fringed with 

 numerous long hairs ; the acicle is of moderate size and extends beyond the distal end of 

 the penultimate joint, while its surface is pubescent ; the external prolongation of the 

 second joint is fairly well marked. The terminal joint of the antennular peduncle 

 extends very slightly beyond the tips of the eye-stalks. 



The chelipedes are of equal size and in every respect similar to one another, belonging 

 essentially to the form which is characteristic of the genus Clihanarius; the merus is 

 trigonal, with the surface smooth, but the borders are dentate and fringed with hairs ; the 

 three terminal joints are remarkably hirsute, the hairs long, of a reddish colour, and arranged 

 in tufts, more sparingly met with on the inner surface ; the outer surface of the carpus
