finger four or five of irregular disposition. The dact3 7 li of the last 

 three peraeopods are simple and rather stout. 



The dorsal spines of the telson (text-fig. 46), by their size and 

 position, afford a ready means of distinguishing the species from 



P. brevicarpalis. The terminal spines 

 also are longer. The outer uropod is 

 nearly 2 "5 times as long as broad, with 

 a single movable spine near the end 

 of its outer margin as in the allied 

 species. 



The largest specimen is an ovigerous 

 female about 17 mm. in length. 



In life the species is almost com- 

 pletely transparent with a faint brown- 

 ish tinge and with transparent eggs. 

 It can only be detected with difficulty 

 as it crawls among the short tentacles 

 of the anemone. 



In many of its characters P. inorna- 

 tus resembles P. diversipes. The latter, 

 however, is a much more slender spe- 

 cies, with highly arched rostrum and 

 with the foremost dorsal tooth not 

 placed so near the apex. The fused part of the outer antennular 

 flagellum is much longer than the free part of the shorter ramus 

 and is composed of 7 to 9 segments, and the antennal scale is 

 narrower and more sharply pointed distally. The second peraeo- 

 pods of type b in P. diversipes are not unlike those of P. inornatus, 

 but the fingers in this type are always more than half the length 

 of the palm.

On both occasions the species was found on anemones of the 

 genus Discosoma in company with P. brevicarpalis.
