286 DR. J. MURIE ON THE ORGANIZATION OF THE CAAING WHALE. 
open outwardly by a small slit containing a retracted nipple, in this case apparent, but 
only imperfectly pronounced. The glands themselves have a tough fibrous external 
coat, and are surrounded by a strong constrictor muscle. 
The male organs of generation of Globiceps* have been described by Jackson; they 
resemble those of the Dolphin. He says, ‘connected with the vasa deferentia, and 
forming undoubtedly a part of the genital system, was a canal, 23 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 one third 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 termination the cavity enlarged to 
five or six lines. No glands were seen on the inner surface”*. An organ resembling 
the above was found by the same author in the Sperm-Whale, the Dolphin, and the 
Porpoise*. I take it to be a uterus masculinus; and as I have myself seen it in two 
genera, one may infer its presence in most, if not in all the genera of the family (see 
woodcut anted, fig. 3). 
No sectional representation of the Cetacean penis, to my knowledge, is published, 
although the structures themselves have long ago received elucidation by Hunter* &c. 
I incorporate in the Plates of this memoir, therefore, a drawing (fig. 56) of that of a 
large Fin-Whale’, typical in part of what obtains in the genera of smaller size. 
2. Pelvic Bones, Ligament, and Muscles.—The pelvis in Globiocephalus is represented 
by a pair of short styliform bones (ossa innominata), which, at a moderate distance 
from each other, float free from the spine among the muscular and other tissues near 
the genital outlet. In this female each of these smooth tapering bones measured 
4 inches in length, had a strong resemblance, in shape, to a first rib, concavity inwards, 
or looking towards its fellow. Anteriorly there was an inturned capitulum, as in Orca, 
just behind the neck of which the bone enlarged somewhat, and then tapered gently 
towards the narrow and pointed hind extremity. At the thickest belly-part of the 
bone the diameter was 3% inch, proportionally less in front and behind. There was a 
* In Dr. Williams’s account of the generative parts of the Lewchew Whale he says, “ there was an anomalous 
connexion between the urethra and rectum, near their termination, of a firm, round, imperforate band of a 
tendinous nature, half an inch in diameter, the use of which was not at all apparent,” 7. c. p. 412. Does he 
allude to the retractores ? or the male parts representative of the mammary glands?
