callous, raised edges. Proboscides short and club-shaped. Body a 

 minute papilla. 



Length of head 2 lines; breadth 1^ line. Length of neck from 

 1 inch to 1 3 lines ; breadth 1 line. 



Hab. Taken from a species of Brama, off Madeira. (Mus. Brit.) 



5. Tetrarhynchus brevis, Baird. 



The animal is of a white colour, and is very short and thick. 

 The head is large and broad, and the bothria are ear-shaped, rounded, 

 and very much thickened on the edges. The neck is very short. 

 The proboscides cylindrical and of considerable length. 



Length of whole animal 3 lines ; head nearly 2 lines ; neck 1 line. 



Hab. Taken from a species of marine Eel at Madeira. (Mus. Brit.) 



6. Tetrarhynchus quadripapillosus, Baird. 



Head of considerable size ; bothria large, rotundate-oval. Neck 

 long, slender, terminating in an enlarged body enclosed in a sheath, 

 which gives off at its lower part four papilla? disposed in such a 

 manner as to interlock with each other and form a terminating coni- 

 cal point. 



Length of whole animal about 3J lines. 



Hab. Taken from the liver of Alepocephalus, sp., at Madeira. 

 (Mus. Brit.) 



For these three species. of Tetrarhynchus I am indebted to J. Yate 

 Johnson, Esq., C. M. Z. S. 



7. Bothriocephalus (Tetrabothrium) junceus, Baird. 



Bothria four, attached to the head by their face, large and some- 

 what auriculiform. Head elliptical. Neck slender ; first segments 

 very fine, gradually becoming broader, but in no part exceeding half 

 a line in breadth. Apertures of genital organs unilateral. 



Length upwards of 4-i- inches ; breadth of neck y^th of a line ; 

 broadest segments about \ a line. 



Hab. Intestines of the King- Vulture (Sarcorhamphus papa).

April 8th, 1862.— Dr. J. E. Gray, V.P., in the Chair. 



Mr. Gould exhibited to the Meeting and described two new spe- 

 cies of Humming-Birds, which he had recently received from Ecuador; 

 a new Fregilus from the Himalayas, which had hitherto been re- 

 garded as identical with the European bird of that form ; and a spe- 

 cies of Prion, which appears to constitute an additional member of 

 that peculiar genus of oceanic birds. 



The Humming-Birds were named, respectively, Heliothrix longi- 

 rostris and Aphantochroa hyposticta ; the Fregilus, F. himalayanus ; 

 and the Prion, P. magnirostris ; and were thus described : —
