tip; but occasionally these blotches are absent. Small gold spots are 

 sparsely scattered over the whole surface. 



General appearance. — Tadpole small (33.0 mm.), full, and deep 

 bodied. Tail medium in length, tip acute, no flagellum. The dorsal 

 crest not exceeding musculature in depth and extending on to the 

 body not beyond the vertical of the spiracle. The tail in general about 

 medium in depth. Spiracle sinistral, more directed backwards than 

 upwards, far below lateral axis. Eye on the lateral axis, in dorsal 

 aspect on the lateral outline, therefore just visible from below. 

 Anus dextral, opening above the level of the lower edge of the ventral 

 crest. Muciferous crypts not distinct. 



Mouth parts. — Teeth -| or -f . Upper labium fringed with a con- 

 tinuous row of teeth; the papillae extend above and inward beyond 

 the end of upper fringe one-sixth to one-fourth (usually one-sixth or 

 more) of the length of the fringe. The end of second upper labial 

 row extending beyond the end of the upper fringe for about one-fourth 

 to one-sixth of the length of either upper lateral row. The horny 

 beak contained in length from one end of lateral row to end of other 

 lateral row 1.75-2.25 times. Median space between these lateral rows 

 contained two to three times in the length of either lateral row. 

 Inner papillae on sides of labium sparse and one row between second 

 row, of lower labial teeth and lower labial papillae to end of short 

 third row. The first and second rows about equal, from 1.4-1.5 

 times the length of the horny beak. The thu'd row no longer the 

 single row of lower labial papillae. Sometimes this row of papillae 

 is absent when this row enters the labial border, maldng the third 

 row of teeth look like a lower labial goatee. This third row one-fifth 

 to one-third the length of the first or second row of lower labial teeth. 



Measurements. — Length of body (7.0-11.4) in tail (10-22 mm.) 

 1.4-2.1, average 1.65. Width of body (4.4-8.0) in its own length 

 (10.0-11.4) 1.3-1.65, average 1.46. Depth (5.6-6.6) of body 1.06-1.25 

 in body width, average 1.125. Depth of body in body length 

 1.51-1.96, average 1.78. Depth of tail (4.4-7 mm.) in length of tail 

 2.4-3.15, average 2.72. Muscular part (1.8-4.0 mm.) of the tail in its 

 depth 1.75-2.6, average 2.15. Spiracle 2.0-2.6 near the base of the 

 hind legs or vent region (2.5-4.25 mm.) than the tip of the snout 

 (5-9 mm.), average 2.16. Spiracle to eye (2.5-4.0 mm.) 1.0-1.4 

 nearer than to vent, average 1.1. Eye equidistant from spiracle and 

 tip of snout (23/2~4 mm.). Nostril 2.0 nearer eye (1-2 mm.) than tip 

 of snout (2-3.5 mm.). Mouth (1.8-2.5 mm.) 0.8-1.25 greater than 

 internasal space (1.8-2.5 mm.), average 0.92. Mouth contained 

 1.2-2.6 in interorbital distance (2.2-5.0 mm.), usually above 1.5. 

 Internasal space (1.8-2.5 mm.) contained 1.2-2.4 in interorbital dis- 

 tance, average 1.75.
