4. EupAGUKUs MACARDLfc.1. n. sp. Plate XI., fig. 3. 



Near E. laun^inosus DeHaan and £. hrachionuntni Thallwitz, from both of which it differs 

 in having shortish eyestalks and large reniform eyes It also resembles E. s/'inuletitiis 

 Henderson, from which it is at once distinguished hy its shaggy chelipeds. 



Carapace elongate, convex fore and aft, broadened posteriorly. Rostrum 

 hirsute at tip, hardly as prominent as the acute antennal angles of the 

 carapace. 



Eyestalks about three-fourths the length of the anterior border of the 

 carapace, reaching beyond the middle of the terminal joint of the antennal 

 peduncle, and not quite reaching the tip of the antennal acicle : they are 

 stout, and gradually broaden up to the reniform eye: ophthalmic scales 

 narrow-foliaceous, subacute, dorsally concave. 



Outer angle of 2nd joint of antennal peduncle produced into a long 

 spine : antennal acicle curved, setose, reaching anterior third of terminal joint 

 of peduncle : flagellum about twice as long as carapace, nude. 



Chelipeds covered with a long white or grey tomentum, which com- 

 pletely buries the outer surface of the wrist, hand and fingers in a dense 

 shaggy coat, quite obscuring all sculpture. 



The right cheliped, which is much the larger, is not quite twice the 

 length of the carapace: the merus has its lower borders serrulate, its upper 

 border transversely rugulose, and its distal border more or less pectinate ; its 

 under surface when denuded is seen to be thickly studded with papilliform 

 granules : the subcylindrical carpus is as long as the combined ischium and 

 merus and slightly longer than the palm ; its outer surface is beset with stout 

 procurved spines, of which a row just outside the upper border is enlar^Jed, 

 but none of them are visible before the tomentum is removed ; its inner and 

 under surfaces are covered with pearly and subsquamiform granules : the 

 palm is about half again as long as broad, both its borders are very well 

 defined, and — like the corresponding borders of the fingers — very regularly 

 and elegantly serrate ; its outer surface is traversed by a median longitudinal 

 slightly-raised row of enlarged spines, between which and the upper and 

 lower borders a few granules are scattered : the fingers are of equal size, not 

 quite as long as the palm, and have their tips calcareous and crossed : as 

 already stated, the sculpture of the hand and fingers is only visible after 

 denudation. 



The left cheliped does not reach the base of the right dactylus : its 

 merus has the under surface granular and the upper surface transversely 

 rugulose: the upper surface of the carpus carries two raised longitudinal 

 rows of spines, of which those in the outer row are very mucli the stron^^est : 

 the lower border of the palm is spinose and there is a median longitudinal
