dons are confined by a double annular ligament ; the exterior one 

 being continued from the adjoining toe, the inner and stronger one 

 from the sides of the proximal phalanx of the outer toe. 



The second and third toes have two perforated tendons ; one in- 

 serted into the sides of first, and the other into sides of second 

 phalanx. 



Mr. Gould then proceeded to characterize a new species of Pera- 

 meles from Port Essington, and a new species of Dusyurus from the 

 same locality. 



Perameles macroura. Per. corpore suproL nigro et flavescenti- 

 alho penicillato, infra sordide albo ; pills rigidis obsito ; caudd

The P. macroura greatly resembles the P. nasuta, having the same 

 elongated form of head, character of fur and colouring, but is distin- 

 guishable by its longer tail. 



Dasyurus hallucatus. Das. supra flavescenti-fuscus, nigro- 

 penicillatus, maculis albis ornatus ; corpore infra albo ; caudd im- 

 maculatd ad apicem nigrd.

This species most nearly resembles the Dasyurus Geoffroii, but is 

 of a smaller size, and has the thumb of the hind-foot more developed. 

 Accompanying the specimen from which the above description is 

 taken was another individual, which diflfers only in having the 

 ground-colour of the body nearly black ; hence it would appear that 

 the present species is subject to the same kind of variation in its 

 colouring as the Dasyurus Maugei, the black variety of which has 

 received the name viverrinus.

Mr. Couch states, that in the month of August 1841, several indi- 

 viduals of this little fish were found swimming at the surface of a 

 large pool in the rocks near Polperro, where they had been left by 

 the reriading tide, having been swept thither by a continued south- 

 west wind, which had also driven in many individuals of Motella
