de Haan, and suggested that these supposed species were also 

 identical with L. pulcherrima, Miers, and with L. urania, Herbst. 

 To these synonyms I would now add L. ornata, Miers, from 

 Ceylon, which is especially distinguished by its carapace being 

 more strongly punctate. This character, however, may prove 

 to be variable in the same way as the granulation of the 

 carapace in some other species of Leucosiidse {e.g. in FMlyra 

 sGcibriusGula) is variable. 



Leucosia urania inhabits the Indian Ocean, the Chinese and 

 Japanese seas, and occurs also on the shores of New Caledonia.

A young male specimen was collected in the Mergui Archi- 

 pelago, which I refer viith some doubt to Pseudophilyra Soedtii, 

 described by me five years ago from two specimens captured on 

 the coast of Amboina. 



It differs from the type specimens of P. Hoedtii, one of 

 which I have before me, in the following characters: — The 

 external angles of the posterior margin of the cephalothorax 

 are not rounded, but rather acute, dentiform, and slightly pro- 

 minent. Stimpson many years ago proved this to be a youthful 

 character of the Leucosiidae (Proc. Acad. Nat. Sci. Philad. 1858, 

 p. 159, Leucosia vittaia). 



The hepatic regions are slightly more concave, so that the 

 anterior half of the cephalothorax is a little more produced 

 than in the type specimen of P. Hoedtii, and the outer foot-jaws 

 are comparatively a little more elongate, the merus-joints and 

 the palps being a little longer and more slender in proportion to 

 the ischial joints. The anterior legs are scarcely longer than 

 the cephalothorax, whereas, in the adult type specimens, they 

 are about once and a half as long ; they present, however, 

 the same distinctive characters. 

 ' I presume that these differences are to be ascribed to the 

 youthful state of the specimen ; but a careful study of a large 

 series of individuals can alone decide this question. 



Having re-examined the type specimen of P. Hoedtii, de Man,
