1. BALiENA. 3 



e. Cast of left tympanic and periotio bones. 

 Atlantic coast of N. America. 



From type of B. cisarctica, Cope, P. Ac. Philad. 1865, p. 168. 

 This is probably the true B. biscayensis, if this is a distinct 

 species. Eoyal College of Surgeons, 1884 [P.]. 



/. Left tympanic and periotic bone. (1469 d.) 



Dr. ManteU [P.]. 

 Labelled by Dr. Gray " var. depressal" ; described in Cat. 

 S. & W. p. 93 (1866), as a variety. 



g. Mutilated left tympanic bone. (1469 e— 52. 1. 23. 9.) 



Labelled by Dr. Gray " Balcena australis, var. depressa." 

 Described (he. cit.) as indicating " an allied species or only a 

 variety." It is not typical of B. australis, but is rather interme- 

 diate in character between the tympanic of that species and of 

 B. mysticetus. Purchased, 1852. 



h. Cervical vertebrse (united). (338/— 53. 1. 5. 2.) 



Dredged up off Lyme Regis. Rev. H. Beecham, 1853 [P.].

 ". Stated to be probably B. biscayensis (p. 84).

 vi. pp. 198 & 204 ; Suppl. Cat. S. & W. (1871) p. 46, where it 

 is stated " this massive vertebra has no affinity with B. biscayensis,

 seas."

 britannica" (P. Z. S. 1873,,pp. 140, 141).
