There are some differences in the shade of coloring in the preserved specimens, some being darker, some lighter than the type. In two the lateral dark-edged, cream spots extend to the axilla, and the light and dark markings on the front and back surfaces of the leg are much more distinct in most of the specimens than in the type. When the specimens are submerged in water, the black bars on the limbs are evident in all specimens. The tympanum is sometimes darker, sometimes lighter than its surroundings. In the field notes of Mr. Dalquest I find the statement that the color in life is bright yellow, which presumably applies to all of the specimens. No trace of this color remains at the present time. The ventral granules of some of the paratypes are very unequal in elevation, some being elongated, nipplelike. The following table gives the variation in measurements of the type and paratypes: Measurements of _Hyla proboscidea_ in mm. =======+=======+========+=======+=====+=====+==========+========== | Snout | | | | | Foot and | | to | Head | Head | Arm | Leg | longest | Eye | vent | length | width | | | toe | diameter -------+-------+--------+-------+-----+-----+----------+---------- 23626 | 58 | 20 | 18.6 | 29 | 86 | 39 | 5 23625 | 56 | 19 | 18 | 29 | 81 | 37 | 5 23627 | 53 | 18.5 | 17 | 30 | 81 | 35 | 5 23624 | 50 | 16.8 | 15.5 | 26 | 70 | 29.8 | 5 23628 | 50 | 17 | 16 | 28 | 71 | 30 | 5 -------+-------+--------+-------+-----+-----+----------+---------- _Relationship._--It would appear that the relationship of this species is with _Hyla bistincta_, a widespread Mexican species likewise occurring in the same general area but at a much higher elevation. It also has an elongated flap which carries the anal opening nearly to the level of venter but the terminal part lacks the triangular flap. There is no prolongation of the snout tip. There are also numerous other differences, so that it would be difficult to confuse the two forms. _Remarks._--This adds another very distinctive species to the Veracrucian fauna. Despite the fact that this state has probably been explored at greater length than any other Mexican state it still is a likely place for the discovery of novelties. _Transmitted April 8, 1948._
