190 THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 



Dorsal fin unusually small and thin and situated behind the line of the genital 

 orifice. 



The dorsal fin of this specimen was sent to Eschricht in salt, and is described 

 by him as follows (36, 378) : 



" The fin itself, extremely small (4 inches high) and flat and narrow, with the 

 point curved backward, stood on a thick tuberous root, which apparently might 

 be regarded as the base of the fin." 



* 



Eschricht also received from Holler one of the pectoral fins, of which he gives 

 a description and figure (36, 379). He found that it was quite different in form 

 from the pectorals of the Humpback and Little Piked whale, and that the pha- 

 langes were 5, 5, 6, 3. Its length was ^ the total length of the whale. 



Holler's measurements of the exterior were as follows :

While considering that the identity of this specimen could not be positively 

 determined, Eschricht, with his usual sagacity, reached the conclusion that it was 

 probably the .same as the celebrated Ostend specimen. In this he was entirely 

 justified. The Ostend specimen is now known to have been a Sulphurbottom, . 

 musculus (L.). 



Holler's measurements, reduced to percentages of the total length and compared 

 with the average of the ten Newfoundland females of B. musculus, measured by 

 myself, are as follows :
