 SPONGICOLA, DeHaan. 



Spongicola, DeHaan, Fann. Japon., Crust., p. 189 : Spence Bate, Challenger Crust. Macrnra, p. 213. 



Body smooth, not compressed. Rostrum short, laterally compressed. Telson 

 dorsally-spinose, bluntly rounded off, about as long as the caudal swimmerets, 

 the outer of which has no transverse fissure. 



Eyestalks short, eyes well developed. Antennal peduncle short, supporting 

 two flagella of moderate length, the basal joint not concave dorsally. Antennal 

 scale of good size. 



Mandible with incurved 3- jointed palp. The 1st and 2nd maxillipeds have 

 well developed exopodites, but the exopodite of the external maxillipeds is a 

 mere rudiment. 



First 3 pairs of legs chelate, increasing in length in posterior succession : 

 the 1st pair slender and equal ; the 2nd pair stouter, equal or unequal ; the 3rd 

 pair much the stoutest, equal or unequal, with a short trigonal carpus and a 

 large broad hand. 



The 4th and 5th pair of legs end in a very short bidentate or tridentate 

 dactylus, and have all their joints simple. 



The abdominal appendages behind the 1st are biramous. 

 Eggs of good size. 



My material does not permit me to speak as to the branchial formula, but 

 it is stated by Spence Bate to be as follows : 



Somites and p 0( jobranc}iiiB. Artl.i'obraiiehise. Pleurobranchiae. 

 Appendages.

88. Spongicola andamanica, n. sp. Plate II. fig. 2. 



Some of the points in which this small species differs conspicuously from S. venusta are italicized. 



Rostrum dorsally serrated, reaching a little beyond the eye. A tiny orbital 

 spinule and a small spinule beside the base of the rostrum are present on either 

 side, as well as a row of small spinules running behind and parallel with the anten- 

 nal portion of the anterior border of the carapace. 



Telson with two longitudinal rows of spines dorsally ; as long as the caudal 

 swimmerets, of which the outer edge is serrated.
