186 SALMONIDJE. 



in the form of the maxillary. Beside the specimens in the British 

 Museum, I have seen another example from the Museum at Haslar 

 Hospital, also stuffed and 22 inches long, presented by Sir J. Richard- 

 son to the latter institution, but without indication of- locality. 



17. Coregonus sapidissimus. 



Whitefish of Lalie Superior. 



Coregonus albus, Thomps. Nat. Hist. Verm. i. p. 143 (with a wood- 

 cut). 

 sapidissimus, Agass. Lake Super, p. 344. 



B. 9 (10). D. 13. A. 14. V. 12. 



The height of the body is about one-third of the total length (with- 

 out caudal) ; the length of the head one-fifth (the caudal included). 

 Snout cut obliquely, sloping over the lower jaw. Maxillaries short, 

 thin, elongate, attaining the anterior margin of the orbit. The an- 

 terior margin of the dorsal fin corresponds to the middle of the dis- 

 tance between the end of the snout and the base of the caudal. 



Small specimens (not exceeding 8 inches in length) have the body 

 somewhat lower, the greatest depth slight]-^ exceeding the length of 

 the head, which is one-fifth of the total, without caudal. 



Lake Superior. 



18. Coregonus latior. 



Agassiz, Lake Sy,perior, p. 348. 



B. 8. D. 14. A. 13, V. 11. 

 The height of the body is one-fourth of the total length (without 

 caudal), the length of the head one-fifth. Maxillaries broader than 

 long ('?), passing beyond the anterior margin of the orbit; snout 

 overlapping the lower jaw, but less than in C. sapidissimus. 



In specimens 7 inches long, the height of the body exceeds the 

 length of the head, and is one-fourth of the total, without caudal. 

 Lake Superior. 



19. Coregonus novae Angliae. 



The Shad- Waiter. 



Coregonus nov-angliee, Prescott, SiUim. Amer. Joum. 1851, xi. p. 342. 



The height of the body is contained nearly six times in the total 

 length (with the caudal), the length of the head more than six times. 

 The diameter of the eye is not quite one-fifth of the length of the 

 head, and less than the extent of the snout. Snout truncated ob- 

 liquely, and shut over the lower jaw, which is shorter. L. lat. about 

 90. (Prescott.) 



River Winnipisseogee (New Hampshire) • specimens 8y^^ inches 

 long. 



A second species, Coregonus neo-hantoniensis , described by the 

 same author (p. 343) and from the same locality, where it is called 

 " Whiting," is so insufficiently characterized that we are unable to 

 decide whether it shoidd be introduced into the list of species.
