REPORT ON THE ANOMURA. 7 



Spiropagiirus elegans, Miers. 



Spiroi^agimis elerjajw, Miers, Ann. and Mag. Nat. Hist., ser. 5, vol. viii. p. 278, pi. xvi. fig. 5, 1881. 



Habitat- — Station VIIp, ofl' Gomera, Canaries, February 10, 1873 ; depth, 78 fathoms; 

 bottom, volcanic sand. An adult male without the right chelipede. 



This species is very closely allied to the last, and distinguished chiefly by the absence 

 of pilifcrous lines from the chelipedes. The type specimen came from Goree Island, 

 Senegambia. 



Genus Anapagiirus, Henderson. 



Anapaguriw, Henderson, Clyde DecapoJa, Trans. Nat. Hist. Soc. Glasgow, p. 27, 188G; Proe. 

 Piny. Phys. Soc. Ediu., vol. ix. part i. p. 73, 1886. 



Anterior portion of the carapace depressed, the cervical groove deep ; front with the 

 rostral projection but slightly marked. Ocular peduncles usually short and stout, with 

 the cornese dilated ; the basal scales of moderate size and separated by a considerable 

 interval. Antenna! acicle slender, the flagellum usually ciliated. Chelipedes unequal, 

 the right larger (in adult males the disparity in size is often very striking), the fingers 

 moving in a horizontal plane and calcareous at the tips. Ambulatory limbs long and 

 slender, the dactyli but slightly ciliated. Coxa of the fifth left leg in the male with a 

 short, curved, membranous organ (formed by the protruded external portion of the vas 

 deferens). Species of small size. 



Anapagurus was originally described as constituting a subgenus of Spiropagurus ; 

 I am now, however, of opinion that it is entitled to rank as a separate genus. It is 

 distinguished from the latter by the form of the chelipedes, ambulatory limbs, and sexual 

 appendage. 



The following species are referable to this genus : — 



Anapagurus chiroacanthus (Lilljeborg), Scandinavian and British Seas. 



Anapagurus hyndmaiini (Thompson), British Seas. 



Anapagurus laevis (Thompson), Scandinavian and British Seas ; Mediterranean, 



in deep water (" Travailleur"). 

 Anapagurus p)usillus, n. sp., Azores, Canaries, and Cape of Good Hope (?). 

 Anapagurus aiistraliensis, n. sp., New South Wales. 



Anapagurus pusilhis, n. sp. (PI. VII. fig. 7). 



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

 extend as far as the end of the penultimate joint of both the antennal and the antennular 

 peduncles ; the cornese are moderately dilated, and the ophthalmic scales are long and 

 acuminate. The antennal acicle slightly exceeds the eye-stalk ; the external p'olougation
