(d) Cestodes—One of the Norwegians drew our attention to a 
large number of soft white bodies embedded in the blubber of one 
of the Sperm Whales. They occurred in a more or less irregular 
manner at a depth of from 13 to 6 in. from the outer surface. Hach 
body is enclosed in a cyst with fibrous walls from which it is readily 
detached. The accompanying figure (fig. 2, No. 3) is taken from a 
specimen in good condition and undistorted. Sections of these bodies 
clearly demonstrate that they are the cysticercus stage of some Cestode. 
The proscolex occurs at one of the poles of the long axis. The 
Prince of Monaco’s account of the capture of a Sperm Whale off the 
Azores in 1895 mentions numerous cysticerci in the blubber of that 
animal, which are probably identical with those here described.” 
(e) Structure found in the renal veins and posterior vena cava 
(see figs. 3 and 4), 
In whale No. 8 3, while searching for the suprarenal, we came 
across a series of short, digitate processes, hanging into the lumen 
of the vena cava at the point of entrance of the renal vein. A similar 
structure occurred in whales Nos. 12 3, 13d, 27 3, 302, 324, all 
Finners. In two of the Blue Whales, Nos. 17 2 and 33 2, it was 
also present, as well as in Megaptera, No. 28 ¢, but in the last in 
a somewhat different form. In some specimens, owing to the manner 
in which the kidney was cut away from the body in removing the 
entrails, it was impossible to say whether the structure had been 
present or not. No trace of it was found in any of the Sperm Whales 
examined. 
; The specimens preserved are four in number, all differing from 
one another. The accompanying figures show the two larger speci- 
mens. Fig. 3 is an example of the most digitate form. This 
specimen is not actually in the renal vein, but projects from the wall 
of the vena cava close to the point of entrance of the renal vein. 
The digitate processes are not actually tubular, but contain cavities, 
- which in the free ends are nearly continuous, so that the whole 
process is here practically a blind sac. The diameter of the processes 
increases from the free end towards the wall of the vena cava. The 
digitations unite at the point of attachment, and the structure thus 
formed is continued beyond the wall of the vein towards the kidney. 
Tt is most unfortunate that we were unable to preserve a specimen
