366 Mil. W. F. LANCHESXER OX THE [Dec. 2, 



Log. Patani. Five specimens from Natica, witli anemones. 



The flagella of the antennse are fringed along their whole 

 length with longish hairs ; this point is not noticed by Hendei'son 

 in his description or figure. 



14. Diogenes rectimanus Miers. 



Bioyenes rectimanus Miers, ' Alert ' Crust, p, 262, pi. xxvii. 

 fig. C (1884). 



Log. ? One small specimen from Afii.rex, and several, 



very small, from shells of Rissoa, Gibbula, and jVeritiua. 



The largest specimen has the carapace only 4| mm. long, and 

 large chelipede only 9 mm. long : to their small size it is probably 

 due that the spines on the lower l)oi-der of the hand of the larger 

 chelipede are scarcely prominent, while the arrangement of the 

 gi-anules on this leg is more obscure. 



15. Diogenes senex Heller.

 fig. 3 (1865). 



Log. Pulau Bidan, Penang. A female, with oA-a, from Alvrex. 



I cannot discover the ophthalmic process in this specimen, l)ut 

 it is probably safer to consider it as having been accidentally 

 broken off, for otherwise the resemblance of the specimen to 

 Heller's description and figure is complete ; the hands only of 

 the larger chelipede and the ambulatory legs would seem to be 

 even more densely hairy than as shown in his figure. 



16. Diogenes desipiens, sp. nov. (Plate XXXIY. figs. 1, 1«.) 



Log. Pulau Bidan, Penang. A male, from Gancellaria. 



This species is characterized at first sight by its extremely 

 short, broad ophthalmic process, and the great liaii-iness of the 

 legs and luider surface of the body. 



The anterior portion of the caiupace just Ijehind the front 

 (which is raised into a smooth distinct lidge) is covered with 

 large, coai'se, somewhat scattei-ed gi-aiuiles over a small area ; 

 behind this area is a deep, transversely-plnced groove, convex 

 towai'ds tlie front and not continued towards the lateral margins, 

 behind which groove the carapace is smooth, except for the very 

 narrow portion enclosed within the groove, which is coarsely 

 punctate. The sides of this part of the cai'apace are thickly 

 liaiiy, and rough gi'anulate (almost rugose posteriorly) beneath 

 the hairs ; the l)i'aiichial i-egions ai-e somewhat swollen, smooth, 

 with a few longish hairs; the V«h:iped suture of the gastric 

 region is distinct. The rostrum is bluntly pointed, triangulai-, 

 with a broad base, and I'oaches as foi'ward as the latei'al teeth ; 

 between these and tJie rostrum the front is concave. 



The ophthalmic scales are longer than broad, and rounded 

 distally where they cany some long hairs ; the ophthalmic process 

 is short and broad, reaching barely halfway along the scales, with 

 its anterior edge microscopically denticulate. Ocular peduncles
