Indian Deep-sea Crustacea. 15 



the teeth that occur in P. Agassizii being here rounded off 

 instead of acute. 



(3) The ophthahnic scales seem to be even less con- 

 spicuous, and the eyes seem to be even more reniform. 



(4) '^i'he antennal spine and acicle are less sharply serrated. 



(5) The high serrated carpal crest that overhangs the 

 base of the hand is cut into two unequal lobes ; the anterior 

 surface of the hand, when denuded of its mat of hairs and 

 bristles, is pitted rather than granular, and the edges of the 

 hand are rather less acutely serrate. 



(6) The first two pair of legs when fully extended reach 

 beyond the tips of the fingers. 



(7) The first abdominal tergura, in the male only, is rather 

 more exposed ; all the abdominal terga are almost hairless ; 

 and the posterior edge of the sixth tergura is excised. 



In all other respects this species agrees exactly with the 

 description and figures of P. Agassizii in the Memoir cited. 

 Its habits, however, seem to be somewhat different, for 

 whereas P. Agassizii was found burrowing in hard sand and 

 in sponge, all our ten specimens were tightly impacted in the 

 natural hollows of decaying driftwood that had sunk to the 

 bottom — e. g. sticks of mangrove and bamboo. 



Colours in life : upper surface of carapace and legs orange, 

 lower surface whit'^, eyes brown, eggs bright yellow. Spirit- 

 specimens are cream-colour, with a metallic iridescence oa 

 the gastric region and on most of the abdominal terga. 



Off east coast of North Andaman Island, 185 fathoms. 



[I regret that in my list of Crustacea common to the 

 " continental slopes " of the East and West Indian regions, 

 published in Ann. & Mag. Nat. Hist. ser. 7, vol. ii., August 

 1898, pp. 140-111, this species appears as Pylocheles 

 Agassizii. — A. A.]

This is closely related to P. verrucosa (Dana), with a 

 * Challenger ' duplicate of which species from Magellan 

 Straits it has been compared. It difiers chiefly from P. verru- 

 cosa in the following respects : — 



The antero-lateral and lateral borders of the carapace are 

 more irregularly and much more aculely spiny.
