1875. ] ON GUATEMALAN LAND-SHELLS. 647 
out again. How, under any other theory, can the discovery in 
similar places of remains of Gulls and Tortoises be explained? The 
effect of a hurricane such as I have described, is to shake off every 
fruit, seed and leaf from the trees. The south-western corner of 
Rodriguez would be peculiarly exposed to its violence, and con- 
‘sequently the animals and birds living on such food would literally 
die of starvation. 
I omitted to mention that I got, both with the mounted bird and 
the male bird, the stones mentioned Ly Leguat as existing in the 
gizzard. In each case they were found on lifting the sternum and in 
the middle of the ribs. They are basaltic pebbles with rough angles 
and surfaces, and no stone of similar kind is to be found within 
about two miles from the caverns. I got four in all, but only two of 
which I could identify the birds they belonged to. 
By last mail, I sent Mr. Edward Newton a specimen of the nearly 
extinct Rodriguez Parrot*. It is probably the Blue Parrot of 
Messrs. Newton’s paper, p. 357; and I have seen several of them, 
though I never could get near one myself. 
I hope shortly to hear of and procure a specimen of the long 
Lizard, called Coulevec, also supposed to be extinct, but which I 
imagine still exists. If one is still to be got, I am sure of it, as I 
have offered a good reward. 
In Malacology there is a very large and interesting field to ex- 
plore, though probably most of our Mauritian species are also found 
there. I got a very handsome collection. As was to be expected, 
the land-shells are peculiar. Remarks on these subjects, I must 
defer for the present, as the mail is just starting.
