Differs from 5. arcuatus var. monslrosus in the following characters :— 

 The eyestalks are not so broad and stout, nor nearly so setose ; but they 

 are dorsally more strongly calcified. The eyes are not so large, and not 



reniform. 



In the right cheliped the carpus is much slenderer, and the upper surface 

 of the palm is defined by two longitudinal sharply-serrated crests, both of 

 which are equally well developed.

Pagurodes, Henderson. 

 Pagurodes, Henderson, Challenger Anomura, 1888, p. 94. 

 Pagurodes is allied to Eupagurus, Catapagurus, and Nematopagurus, but 

 differs from them all in the particular character that the gill-plumes are 

 quadriserial trichobranchiae like those of Parapagurus. The only Indian 

 species that I can now refer to this genus, namely, Pagurodes limatulus 

 Henderson, agrees with Nematopagurus in the fact that the female only (not 

 the male) has a pair of small appendages, modified for sexual purposes, on 

 the first abdominal segment, 



Carapace well calcified in front of the cervical region. Rostrum broad 

 and obtuse. Abdomen well-developed, soft, spirally coiled. 



Eyestalks short and stout : eyes of fair size, ophthalmic scales spiniform, 

 distant. Antennular peduncles long, especially as to the terminal joint. 

 Antennal acicle long, flagellum very long. 



The external maxillipeds are widely separated at base. The exopodites 

 of all three pairs of maxillipeds are flagellate. The palp of the ist maxillfe 

 is non-flagellate (has a rudiment of a flagellum in P. lifuatulus). 



Chelipeds slender and unequal, the right considerably larger : the fingers 

 move in a horizontal plane and the finger-tips are calcareous or slightly 

 corneous. 



The 4th pair of legs are subchelate and the 5th minutely chelate : in 

 both the subterminal " rasp " of granules is present (though very narrow in 

 the 4th pair) as it also is on both rami of the caudal appendages. 



In the male the vas deferens protrudes as a very short curved tube from 

 the coxa of the 5th right leg. 



According to Henderson the males have 3 abdominal appendages, and 

 the females 4, on the left side. [In one species, P. limatulus, the/emalis 

 have also a slender pair of appendages on the first abdominal segment.],*
