The three Hyperoodons recorded to have occurred on the EngHsli 

 coast appeared singly. Two, described by M. Baussard, taken 

 at Honfleur, consisted of a mother, 23, and her young, 12 feet long. 

 Of several captured on the Irish coast, they, on two occasions, ap- 

 peared in pairs. In one of the three instances, two of these whales 

 were secured at the Same time. It would therefore appear that the 

 species was not gregarious. — Thompson, Ann. S{ Mag. Nat. Hist. 

 1846, xvii. 



A specimen was captured in Ballyholm Bay, jiear Bangor,' county 

 Down, on the 16th September, which was 24 feet long and 18 or 20 

 feet in girth at the thickest part. The entire upper surface was 

 blackish grey, the under parts rather paler. The stomach contained 

 the remains of shells and what were called " the feet of fowls," which 

 Mr. Thompson thought might be the beaks of cuttlefish. 



Dr. Jacob says that the oval cavity into which the oesophagus 

 opened " contained a large quantity of the beaks of cuttlefish, per- 

 haps two quarts."— P. Z. S. 1860. 



A female ' whale ' audits young was caught near Whitstable, Kent, 

 and was well figured in the ' Illustrated News ' for 18th November 

 1860, from a drawing by the Eev. G. Beardsworth, who procured for 

 the museum a complete skeleton of the older and part of the ske- 

 leton of the younger specimen, and also a portion of the food found 

 in the stomach. There was more than a half bushel of the beaks of 

 a cuttlefish, probably of the Octopus or sea-spider, and nothing else. 

 An immense number of Octopi must have been eaten to furnish 

 such a quantity; for they are small and were packed close, often 

 one within the other.— See Gray, P. Z. S. 1860, 422. 



2. LAGENOCETUS. 



The crests of the maxillary bones very thick and close together, 

 especially above, where they are flat-topped. The beak of the skull 

 horizontal. The hinder edge of the skull lower than the tops of the 

 crests. Lower jaw straight.
