tation to Didus ineptus. Mr. Strickland, in speaking of it, Says :— 
“A remarkable feature in it is its colossal scale, the Dodo standing 
about 3 feet 6 inches high, and being double the size which the 
picture in the British Museum, the description of eye-witnesses, and 
the existing remains warrant us in attributing to the bird. It is 
difficult to assign a motive to the artist for thus magnifying an 
object already sufficiently uncouth in appearance” (‘The Dodo,’ 
&e. p. 31). Is it not possible that the artist may in this painting 
have taken a life-sized portrait of the large species (Didus nazarenus, 
Bartlett) to which these bones belong? 
In conclusion, I have to state that I should be very glad if these 
remarks were the means of exciting further search for the remains 
of the Dodo and its allies. In Rodriguez the bones must be far 
from scarce, and, as the present instance shows, they may be found 
with little trouble. My brother picked up two of them, as I have 
said, in a cave during a very hasty visit. It is a matter of the 
greatest regret that a regularly organized search is not instituted by 
some resident in that island, or by some visitor to whom time is no 
object. We may depend upon it that a rith reward awaits the care- 
ful explorer of the Mascarene caverns and alluvial deposits,

The specimens sent by Dr. Cooper were all of small size, and, from 
the intercalation of riblets near the margin, clearly immature. They 
presented the incomplete loop of the restricted genus to which Dr, 
Cooper affiliated them. N otwithstanding, as both Davidson and Wood. 
ward state that the young of the British species has the loop similarly 
open, it remained doubtful whether this might not prove conspecific. 
Messrs. Reeve and Hanley unhesitatingly pronounced them to be 
“ caput-serpentis, jun.,’’ the latter gentleman stating that they pre- 
sented the peculiar form of that species which belongs to the Medi- 
terranean examples. Dr. Forbes, however, was fortunate enough to
