of the chcHpedes exliibifc a single pale blue spot on the oulor Kurfacc, 

 and two similar spots on the inner surface— all three near the distal' 

 end of the joint. The ambulatory legs are faintly banded with led. 



The eggs carried by the females are of large size for such a small 

 epecies, and are concealed in the ovigerous sac. They arc even larger 

 than in the next species— Pagnristes puniccus—\n which nioroovor, 

 tliey are freely exposed on the side of the abdomen. 



An adult male gives the following measurements :

The species is characterised by its small size, the nature of its 

 chelipedes, colour markings, etc. In its very short antcniial fliigella 

 it agrees with P. Mans, Henderson, from the Pliilippines, but the two 

 are very different in other respects.

Station 162, off the Madras coast, depth 145 to 250 fathoms. A 

 large series chiefly inhabiting the shells of a Bostellaria, many of which 

 : have an investing Epizoanthus. Several of the females are with ova. 



Station 166, off the Madras coast, depth 133 fathoms. An adult 

 male in the shell of a Rostellaria. 



The median frontal projection is less prominent than usual in the 

 genus, and varies considerably in length in different individuals ; in 

 some specimens the apex is subobtuse, and scarcely reaches the base 

 of the ophthalmic scales, whereas in others it is acute, and extends 

 almost to the middle of the scales. The lateral frontal projections are 

 almost as prominent as the median one. The anterior surface of the 

 carapace is somewhat rugose, with a few scattered hairs, and there is 

 a marginal sulcus following the contour of the anterior margin. On 

 the posteiior membranous region of the carapace, the median or car- 

 diac area is reduced, to a linear elevation, bounded by a sulcus on 

 either side, and the two branchial areas thus almost meet in the middle 

 line. This cardiac elevation widens out slightly in front immediately 

 behind the cervical groove. The e.ye-stalks are shorter than usual in 

 the genus, just reaching the end of the antennal peduncle, or even in 

 some cases slightly falling short of this, and extending to about the
