not so shrill as Acris. It is raucous and grating, it-it /it-it /it-it, some- 

 times 60 times without a stop, sometimes uniform, sometimes double 

 speed. They call from under the grass edges. Sometimes there is a 

 synchronized chorus of sawing notes. 



Breeding: They breed with the spring rains, March 5-May 20. 

 The citrine drab and ivory yellow eggs are in a loose irregular mass 

 attached to plant stems, their number few, 150-175 eggs. The egg is 

 1/32-1/25 inch (0.65-0.9 mm.), the outer envelope 1/12-1/10 inch 

 (2.2-2.4 mm.) or more loose and irregular, the inner envelope 1/16 

 inch (1.4-1.8 mm.). The grayish olive tadpole is small, 7/8—1 1/5 

 inch (23-30 mm.), its crests nearly transparent, the tooth ridges 2/3. 

 After a tadpole period of 30 to 45 days, they transform, April 1 to 

 June 20, at 5/16-1/2 inch (8-13 mm.). 



Notes: April 22, 1925. San Benito, Texas. In sedges around a pond 

 one mile south of San Benito, these little transforming frogs were 

 swimming in shallow water. As we try for them, they often duck. 

 They are hard to collect without hurting them, they are such delicate 

 little creatures. They can turn their heads like some other Pseudacris. 

 Found only a few tadpoles in the pond. The species must be through 

 metamorphosis here. This is a beautiful blue water-lily pond. 



Detailed color descriptions of a male and female taken at Beeville, 

 Tex., March 26, 1925, follow: A pair which laid. 



Female. Back deep olive-gray; on sides pale olive-gray above 

 lateral stripe. Spots on back hellebore green surrounded by black. 

 Stripe through eye and along side dark grayish olive. Bars and spots 

 on fore limb like lateral stripe. Stripe on upper jaw cartridge buff with 

 marguerite yellow or primrose yellow in it. Tympanum, brownish 

 olive or light brownish olive. Venter white or pale olive buff or ivory 

 yellow. Under side of hind legs light grayish vinaceous or light brown- 

 ish drab. Iris — upper part of rim marguerite yellow or primrose yellow, 

 rest dotted black and primrose yellow and cinnamon drab. 



Male. Background pale smoke gray also areas of tea green. Spots 

 vetiver green, surrounded by black. Lateral stripe, bone brown. 

 Tympanum, army brown. White or primrose yellow spots on tubercles 

 below vent and on basal insertion of thighs. Throat discolored dark 

 olive buff or more yellowish. Two longitudinal plaits in middle of 

 throat. Iris of this male has also some avellaneous in it and a tendency 

 to a dark lateral bar through it to complete nasal and lateral stripe. 



March 25, 1925. In the two pairs which laid, the females were more 

 spotted, the males more striped. Is this a natural tendency or an 

 individual variation? 



March 24. The male of a third pair is very much striped. An- 

 other male we captured is very much spotted.
