24 Dr. Richardson's Contributions to 



Schneider) is compared in the ' Histoire des Poissons' with 

 the Thyrsites atun of the Cape of Good Hope. The TMjr- 

 sltes altivelis (' Zool. Proceed.' 1839, p. 99) from Port Arthur, 

 Van Diemen's Land, differs but shghtly from the atun. [Vide 

 * Zool. Trans.' vol. ii. p. 118.] 



The Scombei' macrophthalmus of Solander (' Pisces Austr.' 

 p. 44), of which there is a drawing by Parkinson (91), is the 

 Gempylus solaxdri of the 'Histoire des Poissons' (viii. 

 p. 215). It was obtained on the coast of Eahei no-mauwee, the 

 northern divisionof New Zealand. The number of rays is stated 

 by Solander to be according to our notation, D. 181 — lil7, H ; 

 A. IjlS, II, which differs from the quotation in the ' Histoire 

 des Poissons,' where the two spurious fins above and below 

 are not supposed to have been included by Solander in his 

 enumeration of the rays. His words are, " Pinna dorsalis pos- 

 terior 20-radiata, radio primo simplici, reliquis muticis duobus 

 posticis distinctis ideoque spuriis." And " Pinna analis sub 

 pinna dorsali posteriori, illique similis 18-radiata; radio primo 

 spinoso, reliquis muticis ; duobus posticis reliquis distinctis, 

 h. e. spuriis." Parkinson's figure indicates the number of 

 spinous rays distinctly, but the articulated rays are not drawn 

 with sufficient precision to show their exact number.

This fish is common in all parts of the harbour of Port Es- 

 sington, and is captured daily in great numbers by the natives, 

 who name it " milinjidne." It appears to be the same species 

 which the Forsters found at New Zealand, and named macu- 

 latus, and perhaps it is also the same with the aken parah of 

 Russell (141) and the Chorinemus commersomanvs of the ' His- 

 toire des Poissons'; at least the detailed description contained 

 in this work agrees almost exactly with Mr. Gilbert's speci- 

 men, the following exceptions being slight and perhaps only 

 apparent. 



The length of the snout before the eye is more nearly the fifth 

 part of the length of the head than the fourth ; the narrow maxil- 

 lary dilates and is truncated at its lower extremity ; and the scapular 

 bone has an elongated oval shape and not a rectangular one, its ends 

 being much rounded. The supra- scapular is shaped as in commer- 

 sonianiis. The upper profile of the head is scarcely curved. There 

 is only a single row of teeth on the lateral limbs of the jaws. The 

 couchant interosseous spine is very evident when the part is dis- 

 sected ; there are three interosseous bones without rays before it,
