74 THE VOYAGE OF H.M.S. CHALLENGER. 



of the second peduncular joint is well-marked and acute, and a smaller spine is also present 

 on the inner margin of the same joint ; the flagellum is almost naked. 



The right chelipede has three acute spinules on the outer and distal border of the 

 merus, and several curved and acute spines on the inner border of the carpus, towards 

 the outer surface of the latter joint there is a second but very indistinct row of spinules ; 

 the carpus is about equal in length to the propodus (not including the immobile finger), 

 and the upper surface of both joints is finely granular ; the hand is but little dilated, and 

 two slight elevations are present on its upper and inner surface, near the articulation 

 with the carpus. The left chelipede is very narrow ; the carpus possesses two rows of 

 spinules on its upper surface ; the fingers are slightly pubescent and comparatively long, 

 exceeding in length the remainder of the propodus. The ambulatory limbs are smooth, a 

 few spinules alone existing on the anterior border of the carpal joints ; the dactyli are 

 long and but slightly curved, that of the second pair being slightly longer on the left side. 



The above description is taken from a male. In the female the antennal acicle and 

 the external prolongation of the second peduncular joint are both less strongly marked, 

 the dactyli of the ambulatory hmbs are also shorter. 



A full-grown male measures about 8 mm. in length, and females with ova even less. 



In Anapagurus chiroacanthus (LiUjehor g) = Pagimis ferrugineus, Norman, to which 

 this species bears some resemblance, the hand is pubescent, and the ophthalmic scales 

 are shorter, with their apices subobtuse. In AnaiKigiirus l^vis (Thompson), the 

 ophthalmic scales are rounded and their apices obtuse. 



Habitat. — Station 75, near the Azores ; depth, 50 to 90 fathoms ; bottom, volcanic 

 mud. Several specimens ; the original shells have disappeared, leaving an investment 

 which appears to consist of an Epizoanthus. 



Station VIIp, off Gomera, Canaries, February 10, 1873 ; depth, 78 fathoms ; bottom, 

 volcanic sand. Many specimens ; the majority firmly ensconced in shells of Turritella 

 hicingulata, Lam., one individual in a shell oi Nassa limata, Chem. 



Simon's Bay, 18 fathoms. A male specimen, in a shell of Trochus benzi, Krauss. 

 It is with some hesitation that this is referred to the present species, and subse- 

 quent investigation may show it to be distinct. The chelipedes and ambulatory 

 limbs are more hairy, and the dactyli of the latter are ciliated and slightly longer on the 

 right side ; the hand of the right chelipede is more strongly granulated, and a distinct 

 finely tubercular line is present near the outer border. In other respects it agrees with 

 Anapagurus pusillus. 



Anapagurus australiensis, n. sp. (PI. VII. fig. 8). 



Characters. — The anterior portion of the carapace is smooth. The ocular peduncles 

 are long and slender, exceeding the antennal peduncle and reaching the end of the
