Of this genus only one species is with certainty known, viz. Balae- 

 nopt. rostrata (0. FABRICIUS) J. Gray, which offers two varieties: Pteroba- 

 laena minor, variet. groenlandica et bergensis, D. F. ESCHRICHT, the one ob- 

 tained from the North-Eastern coast of N. America, the other from the we- 

 stern and northern coasts of Europe. J. Gray 1 ) from some fragments of 

 the skeleton has with some uncertainty adopted a 2 nd species, under the 

 name of Balaenopt. Swinhoei. It is from the sea in the neighbourhood of 

 Formosa, but our knowledge of it is as yet so imperfect that it is no possible 

 to decide with certainty whether it ought really to be classed under this 

 genus. Professor H. C. L. Barkow 2 ) has described a smaller skeleton of 

 a young Whalebone Whale, preserved in the University-museum at Breslau, 

 which, though in other respects appearing to correspond with the Balaenop- 

 tera rostrata, differs remarkably from that species in the structure of 

 the anterior extremities , on which a thumb with one phalanx are said to be 

 plainly visible; but Barkow has himself declared, that it is by no means 

 certain, that the extremities thus described belong to this skeleton, and 

 Flower and Gray on this account look upon this species as very dubious. 

 According to Eschricht 3 ) it is probable that a species belonging to this 

 genus is to be found at Kamtschatka and the Aleootskia Isles, there some- 

 times kalled Tschikagluch, according to Chamisso, but it is far from likely, 

 that this should be, as Eschricht, in consequence of the similitude between 

 that name and Tikagulik, the Greenlandic name of the Bal rostrata, sup- 

 poses, identical with that species. Another species may probably occur in 

 the northern part of the Pacific. 



3. Genus FLOWERIUS, n. gen. 4 ). 



Form of the body slender and elongated, with rather small pectoral 

 fins, and the dorsal fin small and situated very far bach, somewhat in front 

 of the posterior fifth of the entire bodys lenght. Processus coracoideus and a- 

 cromion strongly developed, proc. coronoideus high. First pair of ribs have
