selves under the name of K. lepturus. It appears to be the same 

 with the Kanguroo-Rat, the Potorous murinus. The specimen 

 brought home by the expedition was from the neighbourhood of 

 Port Jackson ; the head of a second species of the same genus 

 found on Dirk Hatich's Island is the only fragment of the P. 

 Lesueur ; and a skeleton in the Paris Museum differs so con- 

 siderably in the form of the head as to appear to constitute a 

 third species, to which the name of P. Veron is proposed to be 

 given. The only true Kanguroo described is equally unfortunate 

 with the preceding. It is the Kangurus laniger of MM. Quoy 

 and Gaimard, whose name must yield to the prior claim of K, 

 rufus assigned to the same animal by M. Desmarest. 



In an appendix relative to the Seals and the Cetacea^ which 

 forms the fourth chapter, the authours have embodied much curious 

 information with respect to the habits of these animals, the ob- 

 servation of which so seldom falls to the lot of those who are 

 capable of rendering it available to the purposes of science. The 

 common opinion represents the Whales as almost continually 

 throwing up jets of water from their spiracles. That this occa- 

 sionally happens cannot be doubted ; but it is only under peculiar 

 circumstances. In many hundreds of these animals which MM. 

 Quoy and Gaimard observed in the course of their voyage in the 

 Southern Seas, it occurred to them to witness this fact only once, 

 in a Whale which was on shore on one of the Malouine Islands, 

 and which at ebb-tide threw up water from its spiracles, respir- 

 ing at the same time with considerable noise. Much interesting 

 matter is also contained in this appendix relative to the fishery, 

 for which the authours are chiefly indebted to the crews of the 

 diiFerent whalers with which they met ; this, however, we must 

 pass by, and proceed to the enumeration of the new species 

 noticed by them. These include the Fhyseter polycypus^ so 

 named from the protuberances on its back, which is fignred from 

 a drawing communicated by Captain Hammat, but is not de- 

 scribed ; the Delphinus Rhinoceros^ which is black, spotted, with 

 a protuberance resembling a horn on its occiput; the D. albigena^ 

 altogether black, with a large white fascia on each side of the
