la, Spiropagurus spiriger var. profundorum, nov. Plate XIII., fig, 5. 



The only points at which this variety diverges are the following : — 

 (i) The eyestalks are nude and smooth ; (2) the antennal peduncle has 

 no squamosa markings : (3) the antennal acicle is fringed on both edges with 

 very long and regular sets ; (4) the two longitudinal rows of spines on the 

 upper surface of the wrist of the chelipeds extend along the whole length of 

 the joint ; (5) the posterior border of the meropodites of the 2nd and 3rd 

 legs is strongly spinose. 



In all other respects it entirely resembles the typical form.

lb. Spiropagurus spiriger var. lophomeris, nov. Plate XIII., fig, 7. 



As in var. profundorum the eyestalks are nude and smooth, the surface 

 of the antennal peduncle is smooth, and the antennal acicle is fringed with 

 long setje. The spines on the wrists of the chelipeds are fewer: the poste- 

 rior border of the merus of the 3rd pair of legs is spinulose in its distal half. 



The merus of the chelipeds has the upper border carinate, and in the 

 merus of the 2nd and 3rd legs the posterior surface is remarkably flattened 

 and is demarcated from the upper surface by a thin fine smooth carina. 



In all other particulars it entirely resembles the typical form.

ic. Spiropagurus spiriger var. spinosicarpis, nov. Plate XIII., fig. 6. 



As in varr. profundorum and lophomeris the eyestalks are nude and 

 smooth, the surface of the antennal peduncle is smooth, and the antennal 

 acicle is fringed with long setae. 



The chelipeds of the male (but not of the female) are distinctly stouter 

 than the legs. On the upper surface of the carpus of the chelipeds and 2nd 

 and 3rd legs there are three longitudinal rows of spines: there are also some 

 spines on the posterior border of the merus of the 3rd pair of legs.
