velopment of the pelvic bones or the rudimentary leg bones. 
The tail in this species is believed to be comparatively longer 
than in any other of the extremely numerous species of this genus. 
The type specimen was obtained from the trunk of a small 
tree, which was bored full of tunnels by large black ants. It 
probably feeds on the larvae of ants. There are eleven specimens 
in my collection. 
Typhlops iTigosa sp. nov. 
Type. — No. R 97, E. H. Taylor collection; collected at Buna- 
wan, Agusan, Mindanao, July 14, 1913, by E. H. Taylor. 
Description of type. — Head rough, the anterior outline broken 
by depressions between scales along the sutures. Rostral a little 
longer than wide above, not reaching to level of eyes, more than 
one-third the width of head; below the enlarged part about as 
deep as wide, forming a slightly curved hook on snout; rostral 
dimly granular; prefrontal a little wider and somewhat smaller 
than frontal, its posterior point reaching a little beyond level 
of eyes ; frontal as broad as long, the distance from oculars equal 
to distance between nasals, larger than interparietal; supra- 
oculars larger than frontal, wider than deep; parietals much 
larger than frontal, separated by an interparietal, which is 
smaller than frontal; parietal not twice as wide as long; nasal 
with a swollen prominence about and above nostril, which gives 
the anterior head outline a roughened appearance ; nostrils latero- 
inferior, not visible from above; nasal cleft issues from first 
labial and barely passes beyond nostril, not wholly dividing the 
scale; preocular not as wide as, and much shorter than, nasal, 
in contact with two labials; eyes dim, barely outlined; two 
postoculars, the inferior largest, in contact with fourth labial; 
four upper labials, fourth largest, first and second smallest, 
subequal in size ; scales in 26 rows ; tail ending in a sharp spine ; 
479 scales in a dorsal longitudinal line. 
Color in life. — Above brownish to golden yellow, slightly 
lighter beneath. Very little distinction between the two colors 
as they merge gradually on the sides.
