REPORT ON THE REPTILES AND AMPHIBIANS. 
By THomaAs BARBOUR. 
The work this year has been principally identifying specimens 
from the older collections and arranging the study series, for 
convenience, according to Boulenger’s Catalogue of the reptiles 
in the British Museum. This work has been completed so far as 
the identified lizards and snakes is concerned. A card catalogue 
arranged systematically has been finished for these groups. ‘This 
shows that 23 families of lizards are represented in the collection 
by 836 species and approximately 9,000 specimens; there are 
110 types. 
This enumeration does not include material on exhibition or in 
the storage tanks, and of this there is a large quantity. There 
are still some additional types which have not been located. Sev- 
eral recent exchanges and collections are as yet unentered. 
A larger proportion of snakes than lizards is at present unidenti- 
fied and uncatalogued. 
Of the former there are 604 species, 61 types and about 4,400 
specimens. It is the practice to number individually twenty-five 
specimens of a series and consider the rest duplicates. Until 
1912 the material was numbered by lots, all individuals of one 
species from the same place bearing the same number. The Che- 
lonia and Amphibia have not been rearranged, but considerable 
identification has been done in the groups. 
Dr. A. G. Ruthven has examined material from Central and 
South America, and valuable specimens collected upon his recent 
expeditions have been received in exchange. Dr. L. Stejneger has 
also borrowed material for examination. By gift the Museum has 
received from Dr. J. C. Phillips a splendid collection from Sinai 
and Palestine containing several new species and others hitherto 
unrepresented in the collection; many varieties including the types 
of some new species from Mr. C. T. Ramsden, of San Carlos, 
Guantanamo; Bornean reptiles and amphibians from the Sara- 
wak Museum through Dr. J. C. Moulton; Mexican reptiles from 
Colima, from Col. J. E. Thayer; reptiles and amphibians from
