MAMMALS. 79 



towards tail, of a dirty yellowish colour; sides dusky, with 

 conspicuous oblong white streak along middle. Fins and tail 

 black, except a small portion of under part of tail." 



For these measurements and description we are indebted 

 to Mr. Moodie-Heddle. 



Delphinus tursio, Fair. Bottlenosed Dolphin. 



Mr. Irvine-Fortescue sends us the following notes of two Whales 

 which were stranded alive inside Swaribister Pier, in September 

 1888. He was from home at the time, but a friend of his, Mr. 

 Halcro, took the following measurements and description, 

 which seem to refer them to this species : 



" Length, 8 ft. 6 in. ; diameter of bodies, 22 in. (this would 

 give the girth about 5 ft. 6 in.) ; tail, 2 ft. broad ; dorsal fin, 

 13 in. high, about centre of back, i.e. about half-way between 

 head and tail ; dentition, g-i-J." 



" The two were male and female. The species could probably 

 still be determined from the skeleton." 



" This may be the species which I have observed occasionally 

 among the herds of bottlenoses (Caing Whales). They appear 

 to be about 5 ft. long or rather more, and paler in colour than 

 the Caing Whales. The dorsal fin is higher in proportion to 

 their size, and sharper-pointed." 



Delphinus albirostris (/. E. Gray). White-beaked Dolphin. 



We are indebted to Mr. Moodie-Heddle of Melsetter for the 

 following measurements, and the drawing from which our 

 engraving is taken, of a specimen of this species, which is now 

 recorded from Orkney for the first time : Entire length, 

 9 ft. 1 in.; girth at fin, 5 ft. 4 in.; length of mouth, 10J in.; 

 from snout to blow-hole, 1 ft. 2 in.; from blow-hole to dorsal 

 fin, 2 ft. 9 in.; length of dorsal fin along curve, 2 ft. 2J in.; 

 height, perpendicular, of fin, 1 ft. 2 in. ; length of pectoral fin, 

 1 ft. 8 in.; breadth of tail, 2 ft. 6 in.; dentition, |4g.
