Professor Lindley on New Orchidaceag. 381 



(Delphi nus Tursio, Fabr.), a much smaller species, having the 

 snout prolonged somewhat like that of the Hyperoodon, and 

 which is occasionally taken on the British coast. 



The three Hyperoodons recorded to have occurred on the 

 English shores appeared singly. The two particularly de- 

 scribed by M. Baussard* were taken in company at Honfieur, 

 and considered a mother and her young — the one was 23, the 

 other 12 feet in length. Of the seven individuals captured on 

 the Irish coast, they on two occasions appeared in pairs ; and 

 in one of the three instances here copied from newspapers, 

 two of these whales were secured at the same time. It would 

 be interesting to know whether those which have so appeared 

 were male and female — at all events it would seem that the 

 species is not gregarious. 



So very little of the history of the Hyperoodon is known, 

 that it is hoped even the few particulars here recorded may 

 prove an acceptable contribution.
