de Haan, and suggested that these supposed species were also 
identical with L. pulcherrima, Miers, and with L. uwrania, Herbst. 
To these synonyms I would now add LZ. 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 Leucosiide (e. g. in Philyra 
scabriuscula) 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 with some doubt to Pseudophilyra Hoedtit, 
described by me five years ago from two specimens captured on 
the coast of Amboina. 
It differs from the type specimeus of P. Hedtii, 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 Leucosiide (Proc. Acad. Nat. Sci. Philad. 1858, 
p- 159, Leucosia vittata). | 
The hepatic regions are slightly more concave, so that the 
auterior half of the cephalothorax is a little more produced 
than in the type specimen of P. Hedtii, 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. Hadtiz, de Man,
