hare, and than the Lepus variabilis. It was killed in abundance 

 on Melville Island. 



Thirty-two species of birds are noticed as having been seen 

 within the Arctic circle. The characters which distinguish the 

 Rock Grous, Tetrao rupestris, from the Ptarmigan, Tetrao lago- 

 pus, are distinctly stated : but not a single new species is de- 

 scribed in this supplement. Of the eight fish that are mentioned 

 two are described as new, and two others are noticed as doubtful. 

 The two new species are, 1st Blenxius ^o/ara : imberbis, pinnis 

 anali, caudali, dorsalique, unitis : of which one individual was 

 found on the shore of North Georgia. 2d. Corrvs polaris ; im- 

 berbis, capite spinis duabus, operculis spinis quatuor, armatis. It 

 appears that only six species of insects were collected in the high 

 latitude from the beginning of September to the beginning of Au- 

 gust, most of which are described by Mr. Kirby as new : they are 

 1st Bombyi iSaJmi ; cinereous wings incumbent, antennae of the 

 male setaceous, bipectinate at the base, with short rays. " Accord- 

 ing to the modern system this species might probably be regarded 

 as belonging to a new genus, but the specimens are too much in- 

 jured to enable me to get a clear idea of the palpi, consisting of two 

 joints ? if admitted as such it might be named Psychophora. 

 From the length of the tongue it seems to come between the other 

 Bombycidw and Noclua, though in habit and stature it approxi- 

 mates to Phalcena, Fab. It was found in a swampy part of Mel- 

 ville Island." 2d. Bombus arcticus , black, with the base and 

 apex of the thorax and the anterior half of the abdomen pale yellow. 

 Length of the body, male 7 lines, female ] 1 lines. Syn. Apis 

 alpina O.Fabr. Faun. Grwnl. 155, distinct from the Linnean Apis 

 alpina. 3d. Ctenophob a Parrii: black, wings brownish with a 

 white marginal spot towards the apex, surmounted by a black one, 

 tip of the margin of the abdominal segment pale. Length b\ lines. 

 4th. Chironomus poluris ; black, abdomen hairy, wings lacteous. 

 Length 4 lines. 



A small caterpillar and a very minute spider, added to the 

 above, completes the list of Polar insects. 



Of Invertebrate marine animals Captain Sabine mentions thirty- 

 three, which he has arranged according to the Lamarckian system.
