Occurrence. Sixteen specimens of this rather well- 

 known and widely distributed species were taken off 

 Southern Queensland (Reg. Xos. E.6612, 6614, 6616. and 

 P.3584, 3586-8) ; seven males and eight females. 



Seven miles X.X.E. of Bowen, Queensland, 16 

 fathoms (Reg. Xo. E.6620) ; one female. 



Distribution. According to Alcock. this is one of 

 the commonest of the Indian prawns, and its distribu- 

 tion, as given by De Man, is: "Along the coasts of India 

 from the Indus Delta to Hongkong (Alcock) ; East 

 Indian Archipelago (Atjeh; Makassar; fresh water of the 

 river at Maros; Pare-Pare; brackish water of the river 

 Tjenrana at Palima, Celebes) (de Man) ; Philippine 

 Islands (Spence Bate) and at the coasts of Japan 

 (Kishinouye). Haswell records this species from the 

 Endeavour River, Queensland, and, according to Hilgen- 

 dorf, it should also occur at Quelimane [on the east 

 coast of Africa]." Pesta extended its range southward 

 along the East African coast as far as Delagoa Bay, 

 whence he had a single female specimen, while Stebbing, 

 in addition to two further specimens from the same 

 locality, lists a third from even a little farther south, 

 "off South Head of Tugela River, in depth between 12 

 and 14 fathoms." Kemp records Pcna-opxix monoceros 

 as very abundant in the Chilka Lake, Orissa Coast, 

 Bengal, and numerous in the Tale Sap Lake on the east 

 coast of peninsular Siam. 



Remark.*. With this species I identify a cotype of 

 Haswell's P. ma.*tcr.*ii from the collection of the Macleay 

 Museum ; it is an immature male from Port Darwin. Also, 

 three immature male and female specimens from Finche's 

 Bay, Cooktowu, Queensland, from the Australian 

 Museum (Reg. Xo. P.4287) ; these were collected by the 

 late Allan R. McCulloch and identified by him as 

 P. tnastersii.
