Uttered loud cries when they came ashore, so as to alarm 

 the whole neighbourhood. One preserved in the Town 

 Museum at Nice is labelled as having been taken there 

 in June, 1855. 



In general form Risso's Grampus, according to Prof. 

 Flower, closely resembles the Pilot- Whale {Glohicephalus 

 melas). The forehead is rounded, with no proper beak ; 

 but the thick projecting upper-lip is separated by a 

 hollow from the convexity of the head. The flippers 

 are long and narrow, and the dorsal-fin high and falcate. 

 As already mentioned the colour is extremely variable in 

 this species, being either black above and white below, 

 or clear grey, passing into black on the posterior parts, 

 and into white on the belly. But the most remarkable 

 character of the colouration is the manner in which these 

 ground-tints are marked by irregular lines and streaks, 

 running in all directions without any definite ^pattern ; 

 when best developed, each of these lines has a narrow 

 white centre and a black border. In the younger British 

 specimen noted above, the flanks were marked with white 

 stripes, vertically disposed and nearly symmetrical. 



The teeth are confined to the ZoM;er jaw, even in extreme 

 youth, and vary from three to seven on each side, placed 

 in the front part of the mandible. The number of 

 vertebrae is sixty-eight and of ribs twelve pairs. 



Our illustration represents this example as figured in 

 the plate published with Mr. Flower's paper. 



The following are some of the measurements of the 

 adult female specimen described by Prof. Flower : —
