412 DR. J. MURIE ON THE ANATOMY OF THE WALRUS. 
Blood-vessels of the Limbs of Marine Mammals,” in which those of the Walrus are 
described and figured. At the Scientific Meetings of our own Society, held respec- 
tively on the 8th and 22nd November, 1853, two short but interesting communications 
on a Trichechus rosmarus, which lived a few days in the Gardens, were read :—one 
“On its Anatomy,” by Professor Owen; the other by Dr. J. KE. Gray, “On the 
Attitudes and Figures of the Morse.” The works of Arctic voyagers teem with narra- 
tives and descriptions of this creature in its native haunts; and zoologists in number 
have treated on its characteristics. The osteology has been elucidated by Pander and 
D’Alton, Cuvier, DeBlainville, and many others; and the peculiar dentition has evoked 
keen discussion and remarks from a host of writers. But as the scope of the present 
notice is confined mainly to the soft structures and memoranda on the outer aspect, I 
refrain specific mention of volumes and papers other than those above mentioned, 
unless in allusion to points which better follow in the body of the text. Von Baer’s 
collation of authorities, indeed, precludes the necessity of much addition on my part. 
The young male Walrus upon which the following observations were made was 
that which the Society purchased in the latter end of 1867, and which only lived in the 
Gardens some seven weeks or thereabouts. Mr. Bartlett, P. Z.S. 1867, p. 819, has, 
with his usual felicity, commented on the habits and feeding of this creature; and the 
pathological conditions witnessed, with the discovery of immense numbers of a new 
species of Entozoon (the Ascaris bicolor), which is characterized by Baird, are recorded 
in the P. Z. 8. 1868, p. 67. 
Figures drawn from life, with passing remarks thereon, were issued by several pub- 
lications of the day—among others ‘The Field, ‘Land and Water, and the 
‘Tillustrated London News;’ and to these I refer those interested in the current 
literature of the specimen in question. 
II. On THE Ovutwarp CHARACTERS. 
1. Colour.—The Morse received into the Gardens in 1853, depicted with others in a 
group by Wolf’, as likewise that here described, were both of a tawny brown colour. 
This is in agreement with what most travellers and naturalists have stated, though 
Fabricius’, quoted by Von Baer®, and, I suppose, credited by Gray‘, says the colour 
varies with age, black when young, afterwards brown or yellowish-brown, and lastly, 
when old, white. The St. Petersburg specimen closely resembled ours. My friend 
Mr. R. Brown’, who has made repeated voyages to the Northern Seas, avers, “I have 
seen several young Walruses in all stages, from birth until approaching the adult stage, 
and never yet saw them of a black colour. . . . All I saw were of the ordinary brown 
colour, though, like most animals, they get lighter as they growold.” It is strange that
