I have provisionally placed under this specific name a dolphin 

 recently captured at Manly Beach, a short distance from the north 

 entrance of Port Jackson. 



This fine and perfect specimen Mr. Krefi't, with his usual alacrity, 

 at once secured for the Australian Museum, and, under his own super- 

 intendence, when the animal was still alive, had photographs of its 

 external appearance, and various admeasurements of the body, taken. 



Our public institution consequently is now further enriched by 

 another admirable skeleton of a cetacean, in addition to the several 

 others lately acquired of these rare creatures, and also, with an un- 

 usually correct stuffed representative of an extensive group, commonly 

 so greatly caricatured in book illustrations and museum specimens. 



Assisted by Mr. Krefi't, I took the dimensions of many parts of the 

 skull, and find that although these correspond closely in many particu- 

 lars with the similar portions of the skull of Delphinus microps, now 

 Stenorhynchus, marked i, detailed by Dr. Gray in his Catalogue S. and 

 "W. 1866, p. 240, yet the deviations betrayed by the comparison were 

 sufiiciently distinct to dispel any idea of their sameness. 



I am, therefore, led to the belief when taking into consideration the 

 size, external appearance, general colouring, with the exception of the 

 small discal white spot on each fin, the geographic range of habitat, 

 and common occurrence, that this dolphin is probably identical with 

 the one described in 1774 by Dr. Forster, the companion of Captain 

 Cook.
