Porpoise. — Phoccena communis. 

 Jenyns, p 41 ; Bell, p 473, 2nd ed., p Blasius, p 520 ; Clermont, p 149. 

 Common. " The sniffer of the Cornish fisherman. It is 

 sometimes caught in drift nets, and I have known it take a bait, 

 though it commonly proves too strong for the line. The rolling 

 motion of this and some other of the smaller species is caused 

 by the situation of the nostrils on the anterior part of the top of 

 the head, to breathe through which the body must be placed 

 in somewhat of an erect posture from which to descend, it passes 

 through a considerable portion of a circle. They rarely congre- 

 gate into a herd, like the other Delphini, and commonly no 

 more than a pair is seen together." 



Eisso's G-ramptts. — Grampus griseus. 

 Bell, 2nd ed., p 450 ; Blasius, p 523 ; Clermont, p 152. 

 A beautiful specimen of this cetacean, an adult female 10 feet 

 6 inches long, was caught in the mackerel nets, off the Eddystone, 

 28th Feb., 1870. It is now in the British Museum. See Jour- 

 nal of Anatomy and Physiology, Nov. 1870, and Professor 

 Flower's Memoir, Trans. Zool. Soc, VIII. 1. 



Pilot or Ca'ing Whale. — Globicephalus melas. 

 Jenyns, p 12 ; Bell, p 483, 2nd ed., p 453 ; Blasius, p 521 ; Clermont, p 42. 

 One or two have been taken, but I have no record of the times 

 or places. One was brought into Plymouth in April, 1839.
