This Dolphin has been recorded from the South Atlantic Ocean 

 and Cape seas. Pi'obably it should be united with S. mcdayanus 

 Lesson (1826) and S. frcenatus F. Cuvier (1836), and the distri- 

 bution given as Atlantic, Indian, and Pacific Oceans. Its inclusion 

 in the New Zealand fauna rests on a single skull. There is also 

 in the Dominion Museum a mandible which I refer to this 

 species. The tip is broken, but there are 36 alveoli present. 

 Length of ramus 34 cm., of symphysis 6 cm. 



Parapara. — Skull in Dominion Museum. Hector doubted this 

 skull being obtained in the New Zealand area. It, however, bears 

 the legend " Loc. Parapai-a. Hector 1879. Steno attenuatus 

 Gray " written on the premaxillte. The proportions of the skull 

 and the contour of the premaxillae are identical with the type of 

 D. attenuatus figured by Gray (Zool. ' Erebus' & ' Terror,' pi. 28), 

 but there are high fronto-supraoccipital ridges (like the figure of 

 D. dorism. Gray's work). It is a large skull, and the high ridges 

 may be a sign of age. Pterygoids in contact. Teeth missing, 

 alveoli 39, but end of rostrum not quite perfect. Length of skull 

 39*2 cm., of rostrum. 24 cm. ; breadth of skull at sqviamosals 

 16"2 cm., at orbits 14"7 cm. ; breadth of i-ostrum at base 9 cm. /
