 the town of Osaka and in the lagoon at Kasumi-ga-ura. The Chinese examples were

This species, which apparently has' not been recorded ^ since it was originally 

 described by von Martens in 1868, is represented in Dr. Annandale's collection by ten 

 specimens, obtained in the Tai Hu.

The largest male is rather smaller than von Marten's type and is 75 mm. in 

 length ; in this individual, however, the second peraeopods are noticeably smaller than 

 in one only 63 mm. long. 



In the three largest specimens there are a few minute asperities on the carapace 

 behind the eye and below the hepatic spine; the others are almost or quite smooth. 



1 In this respect the specimen differs from the published descriptions of large males of the species. 



^ The specimen which de Man referred to P. asperulus in 1904 is apparently a different species (see p. 261).
