The uropods agree with Professor Smith’s description, 
if allowance be made for the broken tips of the inner ramus. 
The colour of the specimen in formalin was pure white, 
except the eyes. Wood-Mason and Alcock say of their speci- 
mens, “Colours in life transparent cloudy purple, corneae 
milky orange. (In spirit rich orange-coloured and opaque).”’ 
Length, from apex of rostrum to end of telson, 34mm. 
Professor Smith’s specimen between the same points measured 
30mm. He had an adult male specimen, measuring 28 mm. 
The female specimen from 250 fathoms between the Philippines 
and Borneo, which Bate named P. junceus, was 38 mm. long. 
Of the species which Bate named P. gracilis, he had several 
specimens from far distant localities, and various depths. 
The largest, a female, measured 64mm., but he also had 
females (one bearing ova) which w ‘te only 35 mm. long. 
Habitat—The specimen figured, a female with a few eggs, 
was taken with another at a depth of 250 fathoms, 40 miles 
off Table Mountain. The specimen figured by S. I. Smith 
was taken at 225 fathoms, N. Lat. 32° 18’ 20,” W. Long. 
78° 43°. 
The differences from the type which have been pointed out, 
chiefly concern the armature of the pleopods and telson. 
Unless supported by some considerable distinction in the 
second pair of chelipeds, these can scarcely justify any sepa- 
ration of the two forms.

The definition which I gave of this family in 1893 may be 
here repeated :—‘‘ The rostrum is of important size, the eyes 
are not covered by the carapace ; the mandibles may ‘have a 
cutting edge and ‘palp’ or be without one or both. The
