Grenus G-rapstjs, M.-Udw. 



83. GrEAPSUS STEiGOSTis, Herlst. 



Cancer strigosus, Herlst, Krdbben und Krebse, pi. xlvii. fig-. ?• 



Grapsus strigosus, Milne-Edwards, Hist. Nat. Crust, t. ii. p. 87, and 

 Ann. Sci. Nat. t. xx. p. 169. 



Grapsus strigosus, Alph. Milne- Edwards, Nouv. Arch, du Museum Hist. 

 Nat. 1873, t. ix. p. 286, with the quoted synonyms. 



Six specimens (3c?, 3$) were collected, namely, four in 

 Elphinstone Island and two in Frencli Bay, King Island. 



Grapsus strigosus occurs in the E-ed Sea, tlie Indian Ocean 

 (Mozambique, Ceylon, Nicobar Islands), the Malayan Archi- 

 pelago (Sumatra, Celebes, Timor, Amboina), Australia, China 

 (Hongkong), the Loo-choo Islands and New Caledonia. It is 

 said to occur on the coast of Chili. 



Genus Pachtgeapsus, Stimps. 



84. Pachtgeapstis minutus, Alp7i. M.-Edw. 



Pachygrapsus minutus, Alph. Milne- Edwards, Nouv. Arch, du MusSum 

 Hist. Nat. 1873, t. ix, p. 292, pi, xiv. fig. 2 ; de Man, Notes from the 

 Leyden Museum, vol. v. p. 158. 



One male specimen was collected at Owen Island, com- 

 pletely agreeing with the first description and tbe figure. 



The distance between the external orbital angles measures 

 10 millim. 



As this small species has been observed also in the Banda sea 

 and on the coast of New Caledonia, it would appear to be 

 distributed througbout the whole Malayan Archipelago. 



Grenus Ptxidognathus, Alpth. M.-JEdw. 



85. Pyxidognathus Deianiea*, n. sp. (PI. X. figs. 4-6.) 

 Prof. A. Milne-Edwards some years ago established the genus 



PyxidognatlmsioT: a small crustacean, living in fresh or somewhat 

 brackish water in the island of Ovalau (Bulletin de la Soc. 

 Philom. de Paris, Dec. 187 8). I described, three months after- 

 wards, a remarkable species in the Leyden Museum, under 

 the name of Sypsilograpsus Beldeni, n. g. et sp., which was 

 found near Manado, in the island of Celebes (Notes from the 

 Leyden Museum, vol. i. p. 72, 1879) ; and I subsequently recog- 

 nized the form as being probably identical with Milne-Edwards's 

 Pyxidognatlus granulosus (Notes from the Leyden Museum, 

 1883, vol. V. p. 159).
