Pseudaa'is ocularis 219 



taken April 24 were spent; on May 23 three or four females were found un- 

 spent, and numerous ripe females and pairs were taken July 16. This implies 

 ovulation from April 2 4- July 16. 



On the basis of tadpoles we have mature and transforming tadpoles by 

 June 2 8- July i, 1922, July 8 and July 19, just when we recorded heavy egg- 

 laying the year before. This imphes egg-laying in May or last of April. 



In 1923 (1923, p. 34) we gave this species as one of five which started to 

 breed from "May 15 on to June ist." In our notes we variously have it "May 

 25- ," "May 26- July 18," "May i6-August 13" and in 1924 (1924, 



p. 378) it appears May i6-August 21. This last period about represents 

 our knowledge of it in 1924 if we do not consider spent and unspent females 

 and transforming tadpoles. These latter send the ovulation at least to April 

 24 if not before. April 24-August 21 are the extremes of our evidence. This 

 species being a Pseudacris we might suspect it of appearing early but we dare 

 not prophesy breeding before March and possibly it may extend through 

 September to October i . 



Temperature and humidity {See voice discussion). The only record of 

 positive ovulation came from July 15 and 16, 192 1 when temperatures from 

 73° and 76° obtained. This record comes after a hard rain. We have mating 

 records from 72° upwards. As determined under the topic of voice, ovulation 

 probably comes primarily after downpours when temperatures are usually 

 7o°-79°. 



Egg-laying process. In locahties they choose even more shallow places 

 than Hyla crucifer, but were the author to show the eggs fastened to a stick I 

 doubt if few in America could tell them from Hyla crucifer eggs laid in cap- 

 tivity. We got the same captive complements as in this species. They lay 

 in somewhat similar places, have more or less similar individual eggs. We 

 will not be surprised to discover they lay their eggs in a similar way. In fact, 

 we suspect they belong nearer Hyla crucifer than near the other Pseudacris 

 species or Hylagratiosa, Hyla squirella, Hylaandersonii in egg-laying method. 



EGGS 



Attachment, dangers. One specimen, a female (No. 7 114), the specimen 

 where the lateral stripe breaks into mottlings, has large ripe eggs, which are 

 astonishingly large for the size of the frog. This specimen is only 15.5 mm. 

 long yet its eggs are .8-1.0 mm. in diameter. A slight examination of the egg 

 content shows 50 for either side is high and a complement of 100 eggs is the 

 lowest record for any North American Salientia. This female was taken on 

 Mixon's Hammock June 16, 19 12, in some overflow pools with spring frog and 

 toad tadpoles and with transforming cricket frogs. The middle of June is 

 much later than the breeding period for the larger northern Chorophilus 

 which are amongst the first to breed. These small males 12-13 mm. with 

 gular pouches apparent and this ripe female 15.5 mm. with ripe ova, very 

 strongly discredit any belief that these creatures are young forms of a larger 

 form. (Above note of 1912).
