Art. VII. — Observations on a rare British Dolphin. By Thomas 

 Wright, Esq., M.R.C.S., Lecturer on Anatomy and Physiology. 



Impressed with the value of every new fact illustrative of the 

 organisation, history, and geographical range of British Ce- 

 tacea, I send for insertion in your Magazine the following 

 observations on a rare species of dolphin, Delphinus Tursio, 

 shot near Torquay. The individual now before me is the se- 

 cond or third specimen of this species which has been cap- 

 tured within the geographical limits of the British Fauna. — 

 The fact that troops of four or five individuals are frequently 

 seen in company off the southern coast of Devon, sanctions 

 the inference that Delph. Tursio ought to be considered as an 

 indigenous species ; whilst a probable reason for its extreme 

 rarity may be found in the enormous locomotive powers 

 which it possesses, swimming with inconceivable velocity in 

 pursuit of prey, or seeking temporary refuge in the silent depths 

 of the ocean on the most distant appearance of an enemy. 



The capture and preservation of this specimen I regard as 

 an acquisition to British Zoology, inasmuch as it may serve
