656 MISS M. J. RATHBUN ON CRUSTACEA 
the latter is triangulate, with nearly straight sides, and an ob- 
tuse angled tip armed with three pairs of spinules, of which the 
intermediate pair is longest and the outer pair shortest. Uropods 
broad-oval, longer than the telson, the outer pair broader and a 
very little longer than the inner pair. 
Colour. 'The specimen, which is preserved in formalin and gly- 
cerine, is handsomely marked with lines of crimson and purple 3 
on the pleura of the first three abdominal segments there are four 
incomplete oval areas partly outlined with narrow crimson stripes ; 
the same colour forms aring on the end of each uropod, the inner 
ring smaller than the outer; the tip of the telson is also outlined 
in the same colour; within these five areas of the tail-fan, the 
colour is a lighter yellowish-red, Dorsal face of carapace a brown- 
ish-orange. Chelipeds of second pair with a narrow stripe of 
purple at the distal end of the merus, carpus and manus, and « 
more crimson stripe on the distal half of the fingers. The third, 
fourth, and fifth feet have similar purple stripes on the three 
principal segments. 
This species is not very nearly related to any other. It has 
the same rostral formula, . as P. parvus Borradaile (see Willey, 
Zool. Results, Part iv. 1900, p. 407, pl. xxxvi. figs. 3-3), but 
that species is more slender, with lower rostrum and larger eyes.

Hermite, in mantle-cavity of Pinna; July 7, 1912; No. 112: 
19 ovig., about 26 mm. long. 
This corresponds in the main with the description and figures 
given by Miers (Crust. ‘ Alert,’ 1884, p. 291, pl. xxxii. figs. B, b, 
b'). In the Hermite specimen, the telson has at the end four 
sete, the outer pair stouter than the slender inner pair but nearly 
as long; Miers’s fig. b shows five setze, one median and two lateral 
pairs, the outer pair about half as long as the inner. The smaller 
cheliped of the second pair in our specimen has the tooth on the 
dactylus feebly developed, and fitting into a cavity in the fixed 
finger; in Miers’s'type this tooth was not developed, but the 
specimen was smaller. 
Miers described the species from Port Molle, Queensland ; he 
also had a specimen taken from a Pinna at Sharks Bay, West 
Australia.
