the setz at the tip of the telson exceed the lateral spinules in total 
length, The body is smooth. 
Characters of the female.—It measures 54°5 mm. in total length. 
The distal portion of the upper margin of the rostrum is almost 
straight, and extends only as far as the tip of the antennular stalk. 
The tooth-formula is =; the first four upper teeth are on the 
carapace, while the first three are separated by wider intervals 
than the others. The large chelipedes are sub-equal, and are very 
slightly scabrous; the teeth on the immobile finger are absent, 
while the one on the mobile finger is poorly developed. The joint 
measurements are as follows :—

In some respects, this species resembles P. altifrons, Hender- 
son, recorded from Delhi, the River Jumna and Lahore, but in the 
latter the carpus is a little shorter than the merus, and the fingers 
are more than half the length of the palm and are smooth above 
and below. 
We have associated this species with the name of the Italian 
naturalist Nobili, by whose untimely death science has been de- 
prived of an indefatigable worker, more particularly in the field of 
carcinology. While the genus Palaemon was established by Fabri- 
cius more than a century ago, from South Indian specimens, 
Nobili was the first to describe any of these in detail.

Characters of adult males.—The rostrum admits of great varia- 
tion in length and shape; it generally extends as far as the tip of 
the antennular stalk, but in some cases may fall short of this, 
while in others it extends slightly beyond; its depth in relation 
to its length is not very definite. The upper margin of the rostrum 
also varies considerably in the amount of its convexity; in some 
examples this margin is practically straight. The tooth-formula is
