(30 THE VOYAGE OF H.M.S. CHALLENGER. 



and propodus (more especially the latter) is armed with numerous acute, corneous-tipped 

 spines arranged in longitudinal rows, on the upper border of both joints the spines are of 

 large size ; the fingers are densely hirsute even on the inner surface, their opposed edges 

 are armed with tubercular teeth, and their apices have a black horny external margin. 

 The ambulatory limbs are hirsute, the hairs being confined to the margins, the anterior 

 surface of the three terminal joints is armed with spines similar to those met with on the 

 chelipedes, and a few spinules exist on the posterior borders of the mori. The last two 

 pairs of legs are moderately pubescent. 



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

 segment has its sinuous margin "thrown into four lobes. 



Length of body 34 mm., of chelipede 26 mm., of third right leg 41 mm., of ocular 

 peduncle 8 mm. 



This species is characterised by the form of its chelipedes, which are those of a 

 Clihanarius (the fingers moving almost in a horizontal plane as in that genus), though in 

 all other respects it is a true Pagurus ; it thus serves to illustrate the close connection 

 which exists between these two genera. 



Habitat. — Station 212, Celebes Sea; depth, 10 fathoms; bottom, sand. A female 

 specimen, in the shell of a species of Fusus. 



In addition to the above recorded species, the collection contains a Pagurus from off 

 Port Jackson, 30 to 35 fathoms, too young to be satisfactorily identified.

Front with a distinct rostral projection. Ocular peduncles usually slender, the basal 

 scales of small size and situated close together. Antenual acicle short, the flagellum 

 naked. Chelipedes subequal and of similar conformation ; the hand small, with the 

 fingers moving in a horizontal plane, excavated internally, and corneous at the tips. 

 Ambulatory limbs often with longitudinal colour markings, the penultimate pair chelate.
