ON the 28th of February, 1870, an animal belonging to the Order Cetacea was taken 

 in a mackerel-net near the Eddystone Lighthouse, and brought into Plymouth. It was 

 afterwards sent to the Columbia Fish Market, London, was then exhibited in the 

 Kingsland Road, where I first saw it on the 4th of March, and finally lodged at 

 Mr. E. Gerrard's workshop, where the skin and skeleton were prepared for the British 

 Museum, and where the very carefully executed drawings (PI. I. figs. 1-3) which accom- 

 pany this communication were made, by Mr. Sherwin, under my superintendence 1 . 



The animal was a female, and (as afterwards appeared from the condition of the 

 bones) perfectly adult. Moreover there was evidence that she had recently given birth 

 to a calf. 



The principal dimensions were as follows (all the measurements are taken in a straight 



lines with calipers, unless otherwise stated) : — 



ft. in. 

 Length, from anterior edge of upper lip to notch in middle of caudal fin . 10 6 



From upper lip to anterior edge of dorsal fin . . 311 



From upper lip to anterior angle of eye 1 lj 



1 I have much pleasure in acknowledging the great facilities which Mr. Gerrard afforded me in examining 

 both the specimens described in this communication.
