21,2 Taylor: Herpetological Fauna, I 187 
Color (in alcohol, freshly preserved).—Above gray, with 
darker transverse blotches, somewhat darker on the sides of the 
neck; no stripes or markings on the head; tail distinctly barred 
with dirty white on the latter third, dimmer on the median third, 
and very indistinct or wanting on the basal third; limbs mottled 
with darker gray, apparently without bands; below dirty flesh 
white; lamellz under toes dark; no labial markings. 
Remarks.—The specimen was obtained from Batan Islands 
by Gregorio Lopez, who accompanied a relief expedition sent to 
the Batanes by the Government of the Philippine Islands. He 
stated that the specimen was caught in a house by a resident of 
Itbayat Island. 
The species is related in a general way to Gekko japonicus 
Duméril and Bibron and to G. swinhonis Giinther. It differs 
from G. japonicus in the larger number of tubercles on the back, 
the scalation of the forehead, the very much larger number of 
pore scales (which very probably represent the number of 
preanal and femoral pores in the males), and in the markings; 
G. swinhonis differs from the species here described in having 
no tubercles on the back and fewer preanal and femoral pore 
scales. From G. smaragdinus, a new species described in this 
paper, G. porosus differs in color and markings and in‘ the 
shape of the body, as well as in scalation and the number and 
arrangement of the pore scales. 
Gekko smaragdinus sp. nov. 
Type.—No. 260, E. H. Taylor collection; collected on Polillo 
Island, July 12, 1920, by E. H. Taylor. 
Description of type—(Adult male.) Rostral large, bent 
backward over snout, depressed medially but raised in front 
of nostril, bordering nostril; a slight suture enters rostral 
medially above; nostril surrounded by rostral, first labial, a 
supranasal, and two postnasals; an enlarged scale in contact 
with postnasals but not entering nostril; scales on snout equal, 
larger than those on occiput; upper labials larger anteriorly, 
becoming very small near angle of mouth, seventeen on right 
side, eighteen on left; the row of scales immediately above upper 
labials distinctly enlarged; lower labials fourteen and fifteen; 
mental small, rectangular; the rows of scales bordering lower 
labials somewhat enlarged, the two largest separated from 
mental by three scale rows; behind these, some distance on each 
side, is a row of four larger scales separated from labials by 
one scale row; body above covered with minute, equal-sized
