The small collection of Reptiles and Batrachians made by 
Capt. Bottego, the working out of which has been entrusted to 
me by the Marquis G. Doria, President of the Italian Geographi- 
cal Society, is one of special interest both from the point of 
view of the Geographical distribution, and from the unexpected 
percentage of new species it has brought to light. With a few 
exceptions the specimens are well preserved. Capt. Bottego may 
be congratulated on the success of his efforts in this department, 
and if the other groups of animals collected by him, and which 
I understand are at present being worked out by various spe- 
cialists under the direction of the Marquis Doria, furnish similar 
results, he will not have to regret the pains he has taken.
