68 Frogs of the Okefinokee Swamp 



Special: 

 Scaphiopus holbrookii 



1. Experimental zoologists should canvass why its tadpoles develop into 

 frogs in 17-30 days. 



2. Why are sizes from 12-51 mm. scarce in collections? 



3. Even presumptive growth data is scanty. 



4. Food might prove very suggestive. Entomologists collect more fre- 

 quently early night flying insects. 



5. Post breeding studies to hibernation are fragmentary. This is the 

 age-old question about spadefoots. 



6. Why do S. holbrookii and S. couchii, large adults have small tadpoles, 

 and transform at small sizes, and S, hammondii a small ad^lt, trans- 

 form at a large size? • 



Bufo quercicus 



1. More observations on egg-laying process are neded. 



2. The mature tadpole needs to be better described. 



3. Transformation data scanty. 



4. Bufo quercicus as an insect collector of small forms (see Dr. Remington 

 Kellogg's and Professor C. R. Crosby's studies of this form). 



Bufo terrestris 



1. Tadpoles of Bufo terrestris need to be carefully described. 



2. Are its affinities with B.fowleri and B. americanus or with B. valliceps, 

 etc.? 



3. Discrimination or non-discrimination of males at the breeding season. 

 Acris gryllus 



1. How distinct are Acris crepitans and Acris gryllus? 



2. Do 15 mm. transformed frogs breed at once or are they from 9 mm, 

 transformed sizes? 



3. Why superlarvation in Acris? Does it imply diverse larval periods? 



4. Does it regularly lay single eggs or masses? 

 Pseudacris nigrita 



1. We missed its life history completely. Every topic in our outline for 

 each species needs attention. 



2. Is it really different from P. triseriata, P. feriarum, P. septentrionalis 

 and (old) P. clarkii? 



Pseudacris ocularis 



1 . Does it belong in Pseudacris? 



2. More evidence on breeding season. 



3. Egg laying in field. 



4. Larval period problematic. 



5. Probable differences between tadpoles of P. ocularis, P. nigrita, and 

 P. ornata not known. Lends an uncertain element in identification of 

 Pseudacris larvae of southeastern U. S. 



6. This mite of a frog ought in its food to collect unusual forms for 

 entomologists and parasitologists.
