CETACEA. 



As early as the year 1843 Sir R. Owen (Proc. Geol. Soc., 

 Vol. IV., p. 283, and Quart. Journ. Geol. Soc., Vol. L, p. 39, 1845) 

 described some Cetacean remains from the Suffolk Crag as " Fossil 

 Tympanic bones referable to four distinct species of Balsena." 

 These specimens were afterwards more fully described and illus- 

 trated (Brit. Foss. Mamm., p. 526, 1846), and some large teeth, 

 also from the Suffolk Crag, were named Balvenodon physaloides. 

 Until quite recently the names given to these Cetacean remains 

 hnve been almost universally adopted. 



Prof. Lankester in 1864 (Annals, Ser. 3, Vol. XIV, p. 356) 

 gave an account of some Cetacean specimens from the Red Crag 

 which had come under his notice and referred them to Delphinus. 



A ziphioid rostrum from the Red Crag was described by Prof. 

 Huxley in 1864 (Quart. Journ. Geol. Soc., Vol. XX., p. 388), and 

 several species of them were named by Sir R. Owen (Pal. Soc. 

 1870), and by Prof. Lankester (Quart. Journ. Geol. Soc., Vol. 

 XXVI., p. 502, 1870). More recently Mr. R. Lydekker (Quart. 

 Journ. Geol. Soc., Vol. XLIII., p. 7, 1887, and Cat. Foss. Mamm. 

 Brit. Mus., Part v. p. 16, 1887), has revised the nomenclature of 

 the Crag Cetacea, adding several forms not previously recognized, 

 and the following notes on the species are for the most part in 

 accordance with Mr. Lydekker's determinations. 



Prof. Prestwich (Quart. Journ. Geol. Soc., Vol. XXVII., p. 338, 

 1871) has recorded the finding of the Vertebrae of a whale 31 

 feet long in a brick pit at Chillesford ; but the specimen was never 

 properly identified and has, I believe, been since destroyed. 

 Messrs. R. and A. Bell (Proc. Geol. Assoc., Vol. II., p. 215, 1872) 

 notice this specimen as well as another from the Norwich Crag, 

 calling them both Balcena. 



Cetacean remains referable to several species have also been 

 found in the Forest-bed (Mem. Geol. Surv., Vert. Forest Bed, 

 p. 108, 1882 ; Quart. Journ. Geol. Soc., Vol. XLII., p. 316 ; 

 and Geol. Mag., Dec. 3, Vol. VI., p. 145, 1889).
