198 A. Alcock — Carcinological Fauna of India. [No. 1, 



Antennulary flagellum about a third the length of the carapace, 

 not hairy, except at base. 



Chelipeds unequal, both hands covered, on the outer surface and 

 upper and lower borders, with prominent spiniform granules, which 

 also extend some way along both fingers. 



Legs rather short, the longest pair being about half again as long 

 as the carapace. 



Colours in spirit yellow. 



The body is of such depth that the last pair of legs, even in the 

 male, lie, in the normal inclination of the body vertically over the first 

 pair. 



In the Indian Museum is a single male from the Andamans. 



119. Pilumnus de Haanii, Miers. 



Pilumnus de Haanii, Miers, P. Z. S. 1879, pp. 20, 32 ; and Challenger Brachyura 

 p. 155, pi. xiv. fig. 1 : A. 0. Walker, Journ. Linn. Soc, Zool., XX. 1886-1890, p. 110. 



Carapace covered with a very fine and short, but dense, fur : legs 

 and chelipeds with a similar fur mixed with long fine hairs on outer 

 surface of hands and on borders of legs. 



Carapace transversely oval, not three-quarters as long as broad, 

 the regions (when carapace is denuded) fairly well marked and areolat- 

 ed, granular towards the antero-lateral margins and near the front. 



The front is nearer half than two-fifths the greatest breadth of the 

 carapace, is nearly straight, not at all prominent, is finely denticulate, 

 and emarginate in the middle line. 



Orbital margin very finely denticulate, the upper border with two 

 very inconspicuous notches, a fissure below the acute outer orbital 

 angle. 



Antero-lateral border a good deal shorter than the postero-lateral, 

 cut into three shallow anteriorly-acuminate teeth. 



Chelipeds unequal : the outer surface of the wrists with a few 

 granules anteriorly and along the inner border : upper and outer sur- 

 faces of hands closely covered with acute spiniform tubercles which 

 also extend far along the fingers. 



Legs stout, unarmed. 



Colours in spirit, golden yellow. 



In the Indian Museum are 7 specimens from Palk Str. 28 speci- 

 mens from off Ceylon, 26| to 34 fms., only differ from the typical form 

 in having the front more deeply emarginate in the middle line. 



This species, but for the broader straighter front, and for the 

 broader carapace, more nearly resembles an Actumnus than a Pilumnus.
