_ The foetus of Phocena has two bristles on each side of the 
“nose ; as the animal grows, these bristles fall out, and each leaves 
a small pit on the side of the nose, which Klein (Hist. Piscium, 
1. 24) mistook for the nostrils, as has been well observed by Prof. 
Eschricht, 250. 
_ Mr. F. Knox gives many details of the anatomy of this species 
in his ‘ Catalogue of Preparations relative to Whales,’ 1838, p. 32.
