of either lateral row sometimes very narrow (6 in lateral row). The inner 

 papillae extend under the third row of lower labial teeth making at least two 

 rows across the lower labial border. In the lower labial corner there is a 

 heavy papillary series sometimes 3 or 4 rows wide like H. versicolor or //. 

 femoralis. The lower third labial row is long and is usually about the length 

 of the first or second lower labial rows and longer than the horny beak. The 

 first and second rows are about equal and i 1/2-1 3/4 greater than the horny 

 beak. This species, like H. versicolor and H. femoralis has the upper fringe 

 very angulate at the middle. 



Measurements. Length of body (10-12 mm.) in tail (16-20 mm.) 1.55-2.05, 

 average 1.75. Width (5.0-6.6 mm.) of body in its own length 1.7-2.2, average 

 1.875. Depth (5,0-7.0 mm.) of body equals body width, or slightly greater. 

 Depth of body 1.5-2.2 in body length, average 1.81. Depth (6.0-8.0 mm.) of 

 tail in length of tail 2.3-3.3, average 2.8. Muscular part (3.0-4.2 mm.) 1.5- 

 2.33 in depth of tail, average 1.87. Spiracle 1.15-1.75 nearer base of hind 

 legs or vent region (4.0-6.5 mm.) than the tip of the snout (6.5-8.0 mm.), 

 average 1.47. Spiracle 1.4-2.2 nearer eye (2.8-3.5 mm.) than base of hind 

 legs or vent, average 1.7. Eye 1.1-1.6 nearer to spiracle (2.8-3.5 mm.) than 

 to snout (4.0-5.0 mm.), average 1.38. Nostril 1.5-2.4 nearer eye (1.2-2.0 mm.) 

 than snout (2.8-3.5 mm.), average 1.8. Mouth (2.0-3.5 mm.) usually equal 

 to internasal space (2.5-3.5 nim.). Mouth contained 1.1-1.8 (average 1.50) 

 in interorbital distance (4.0-5.5 mm.). Internasal space contained in inter- 

 orbital space 1.33-2.0, average 1.58.

General remarks. In 1923 (p. 406) we characterized these outstanding 

 characters as "bodies greenish, tail uniformly sprinkled with black dots." 



LARVAL PERIOD 



On July 3, 1922, at Trader's Hill, we found the species very active in 

 congress. On August 9, ^^ days later there were "small tadpoles at Trader's 

 Hill ponds. If the tadpoles transforming July 10 ,were laid in the very rainy 

 last week of May, 1922, they were 40-45 days in the larval life. 



The eggs laid in camp July 3-4 hatched July 5 developed by July 30 to 

 tadpoles 1 1 mm. long but proper food conditions were not at hand. Some of 

 them fixed August 21 measured 16 mm, or one-half normal tadpole size 48
