XIV.—Further Contributions to the Anatomy of the 
Sperm Whale (PHYSETER MACROCEPHALUS) based upon an 
examination of two additional Fetus, 
by 
Frank E. Beddard, M.A., D.Sc., F.R.S. 
With Piuate XXIII. 
(Ee present communication is a continuation of an earlier Memoir* 
published in this Journal in 1915. Since then, Mr. Chubb has 
been so very kind as to entrust to me two feetust, both of which are 
much smaller than that which I originally described. This has given 
me the opportunity of adding some further facts to the kngwn 
natural history of this Cetacean, and I have also taken the chance 
thus offered of making a more comparative study of the growth of 
this whale than was possible in my earlier paper, when only one, and 
that a very much larger foetus, was known to zoologists—in addition 
of course to that which I myself described. In that earlier paper, 
however, I did not refer to a short account by Prof. Kiikenthal of a 
comparatively young foetus, but only to that dealt with} by Messrs. 
Pouchet & Beauregard. Kiikenthal’s paper§ had not reached my 
hands until my own notes upon the fostal Cachalot had been despatched 
to Durban. 
The foetus dealt with by Kiikenthal was only studied by him with 
reference to its external characters, and it is represented in his memoir 
by a considerably reduced, but still large, figure, in which most of the 
details are indicated ; other figures are included on one of his plates 
which will be duly referred to in the proper place. The specimen in 
question was 740 mm. in total length, ie. about thirty inches; it is 
thus considerably smaller than the feetus originally treated of by 
myself in this Journal], which has a total length of only twenty inches,

+ Of them the smaller was presented to the Durban Museum by the Premier 
Whaling Co. and the other by the Union Whaling Co. 
t Nouv. Arch. Mus. (38), IV, p. 24. The authors of this paper, however, 
speak of a much smaller fetus (80 em.) of which they give no figures or 
description—save only of the developing teeth (ib. [3] I, p. 84). 
§ Jen. Zeitschr., LI, 1914, p. 84. This paper deals with a number of fcetal 
whales including one example of a Cachalot.
