median space between the second lateral upper labial rows of teeth long, 

 contained 1.2-.75 times in either lateral row, i.e., rarely greater, often equal 

 to and more often greater than either lateral row. The horny beak is con- 

 tained in upper fringe i. 2-1. 3 5 times or 1.3 5-1. 5 times in the distance from 

 one end of lateral row to the end of the other lateral row. There are prac- 

 tically no inner papillae. The first row of lower labial teeth about equal to 

 horny beak or shghtly larger. The second row of lower labium usually per- 

 ceptibly longer than the first row, (the illustration is a little unusual in this 

 respect) .

 2.5-3.25, average 2.9. Width (5.5-9.0 mm.) of body in its own length 1.44- 

 1.9, average 1.66. Depth (4.18-8.0 mm.) of body i. 0-1.3 in body depth, 

 average 1.17. Depth of body i. 625-2.1 in length of body, average 2.0. Depth 

 (4.2-7.8 mm.) of tail in length of tail 3.25-5.0, average 4.0. Muscular part 

 (2.8-4.4 mm.) 1. 2-2. 1 5 in depth of tail, average 1.7 1. Spiracle 1.6-2.36 

 nearer base of hind legs or vent region (3.2-5.6 mm.) than the tip of the snout 

 (7.0-10.0 mm.), average 1.92. Spiracle to eye usually equal to spiracle to 

 base of hind legs or vent. Eye i. 0-1.66 nearer the tip of snout (3.0-4.2 mm.) 

 than to spiracle (4.0-6.0 mm.), average 1.22. Nostril i. 0-1.33 nearer eye 

 (1.4-2.4 mm.) than snout, (1.8-2.8 mm.). Mouth (1.8-2.4 mm.) usually 

 1-1.3 larger than internasal space, (1.4-2.6 mm.), average 1.06, rarely less 

 than internasal space. Mouth contained 1.3-2.2 (average 1.7 1) in inter- 

 orbital distance (3.0-4.6 mm.). Internasal space contained in interorbital 

 space 1.33-2.2, average 1.7.

General remarks. Hay (1892, p. 462) "On the i6th of August . . . found 

 numerous specimens of the tadpoles of this species. They were found hiding 

 in the vegetation at the bottom of a small stream. They were in very dif- 

 ferent stages of development, some with body, the fore and the hind legs 

 visible, others with only short hind legs." In Indiana, Hubbs (191 7, p. 99) on 

 Sept. 23 found "tadpoles of species . . . in the pond, as were also a few 

 transforming individuals." 



The first author to describe the mouth parts of the tadpole is 0. P. Hay 

 (1892, p. 462). He describes them as follows: "The arrangement of the 

 horny denticles about the mouth of the larvae I found to be different from 

 that of specimens of Chorophilus triseriatus. In both species there are two
