A specie praecedente anne distincta?

It appears that Leach considered this as not specifically distinct from Ph. globulosa, 

 which is very probably correct. ^

Of the foregoing species I have only seen specimens of the first two and of the last. 

 Of Ph. scabriuscula there are several in the Banksian Collection of the Linnean Society, 

 in the British Museum, and in my own collection. Philyra globulosa is in the British 

 Museum; and of Ph. platycheira I have a specimen from the Philippines. I have 

 endeavoured to select those characters which are essentially distinctive. Those of De 

 Haan's two new species, I have taken verbatim from his work.

Carapace orbicular, smooth, but not polished ; lateral margin thin, with a minute notch 

 between the hepatic and branchial regions succeeded by a very slight angle, a minute 

 projection over the second and another over the fifth pair of legs, and a small semicircular 

 one on the middle of the intestinal region, the posterior margin flattened and turned up. 

 Front with two small acute teeth in the centre, and two broader ones at the inner canthus 

 of the orbit. The epistome not extending beyond the front. A rather prominent ridge 

 on the pterygostomian region, which is without any granulations. The external foot-jaws 

 with the palp dilated at the outer side, and then narrowed towards the apex ; the buccal
