1: lines across. For about 2 inches before their termination, 
they became quite thin, and the canal increased to 5 lines; 
dilatation not sudden ; opened at last separately on the veru- 
montanum by a small orifice or slit. 
Connected with the vasa deferentia, and forming undoubt- 
edly a part of the genital system, was a single canal, 2j inches 
long, opening on the verumontanum, just in front of the 
vasa, and so closely connected with them as not distinctly 
to appear, except for about ! of an inch just before the vasa 
came together. At this last part, where it terminated in a 
cul de sac, it appeared as large as the vasa, but was thinner, 
and the cavity larger, the inner surface being white and 
rugous. It afterwards became smaller, but, before termina- 
tion, the cavity enlarged to 5 or 6 lines. No glands seen on 
the inner surface. A similar canal was found in the porpoise. 
Prostate large; ducts large and numerous, and o 
on each side of the verumontanum. 
- Penis 11 inches in length, and 1; inches in diameter 
midway ; no septum ; fibrous parietes thick and dense. The 
last 41 inches tapers to a point, and is free, though concealed 
beneath the surface of the body. «Erector muscles strongly 
developed, but the acceleratores less so. A strong retractor 
pair, also, appearing like one muscle, arose near the perineum, 
and was inserted about the commencement of the free portion 
of the organ. FESSA 
The animal having been purchased for the Society; the 
bones were macerated with a view to the skeleton; but they 
were found to be too imperfectly ossified, some of 
epiphyses being not merely separate but scarcely formed. 
The vertebre were 58 in number; bodies of 6 of the 
cervical co-ossified ; 11 dorsal, as stated by Cuvier in the 
globiceps (Oss. Foss. vol. v.); but posterior to these were 40, 
whereas he makes but 37. The cranium corresponded suffi- 
ciently well with his description and figures of the globiceps 
(pl. xxi.), with which it was very carefully compared,
