Hawaiian Monk Seal — King and Harrison 
certain that its venous pattern is that prevail- 
ing in all Laysan monk seals, and it is frustrating 
that the first whole specimen available for exam- 
ination should be congenitally abnormal. 
It is hoped that continuing interest in this 
rare and relatively unknown seal will, in due 
course, result in the acquisition of more speci- 
mens for study. In the meantime it has been a 
great pleasure to see and work on the present 
animal and we are much indebted to Mr. Vernon 
E. Brock and his fellow workers for their kind- 
ness. We are also grateful to Dr. J. D. W. Tom- 
linson for injecting the specimen and for making 
some initial observations. 
SUMMARY 
A young male monk seal Monachus schauins- 
landi of an estimated age of 5 weeks has been 
received by the British Museum (Natural His- 
tory). A brief description is given of the ex- 
ternal features, stomach contents, and parasites. 
The skull and skeleton are described and a gen- 
eral similarity to that of M. tropicalis is noted. 
Certain modifications in the venous system are 
described; coarctation of the aorta is present.
