PSEUDOPHILYRA HOEDTII. 125 



Mr. Miers moreover has shown (Ann. and Mag. of Nat. Hist, 

 for March 1880, pag. 28) Lew. obscura Bell to be the 

 same species. 



Pseudophilyra hoedtii n, sp. 



The genus Pseudophilyra Miers (Proc. Zool. Soc. 1879, 

 p. 40) differs from the true Leucosiae only by the absence 

 of the so-called thoracic sinus , a cavity in the subhepatic 

 region of the carapace , and includes , as far as I am aware , 

 but two species , Pseudoph. perryi and Pseudoph. friden- 

 tata. I now have found in our collection two fine speci- 

 mens , collected on the shores of Amboina by Mr. Hoedt , 

 which by the absence of the thoracic sinus must be re- 

 ferred to Pseudophilyra. Our form may be closely allied 

 to , may perhaps be even identical with Pseudoph. triden- 

 tata Miers of the Corean seas , but unfortunately only 

 the carapace of this species has been described and when 

 the hand which was also figured by Mr. Miers as proba- 

 bly belonging to that carapace , having been found in the 

 same phial (1. c. PL II , fig, 4i), really belongs to it , then 

 our species is quite an other one, for the shape of the 

 hands is quite different. 



In its outer appearance both of the carapace and of the 

 legs , our form closely resembles Leucosia pubescens Miers 

 (Trans. Linn. Soc. 1877, pi. XXXYIII, fig. 22—24). Ca- 

 rapace (front included) more long than broad , punctulated 

 with rather few scattered punctulations. Anterolateral margins 

 a little sinuated in front of the base of the insertion of 

 the chelipedes , beaded by granules , which are largest above 

 the base of the anterior legs and diminish gradually in 

 size towards the front. Posterior margin and postero-la- 

 teral margins defined by a beaded line, the granules of 

 which being largest above the first pair of ambulatory 

 legs and diminishing in size posteriorly, ^pace between 

 the lateral margin of the carapace and the base of the 

 chelipedes a little pubescent without granules. Frontal
