General Discussion 69 



Pseudacris occidentalis 

 Pseudacris ornata. 



1. One species or two? 



2. In either case complete life histories needed. 



3. Will the toadlike P. ornata be as diverse as P. ocularis or P. triser- 

 iata? 



Hyla andersonii 



1. A better color description from life of the female is desirable. 



2. The breeding sizes (30 mm.-4i mm. males and 38-48 mm. females) 

 are apparently lacking in breeding females below 38 mm. and breeding 

 males below 30 mm. 



3 . Is Hyla andersonii in other parts of its range always a sphagnaceous 

 breeding frog? (See R. virgatipes) 



4. What is the hatching period in life? 



5. Larval period needs more evidence. 



6. Transformation period and size needs more observation. 



7. Even presumptive growth impossible because there are so few speci- 

 mens in collections between 15 mm. and 35 mm. 



Hyla cinerea 



1. Is it primarily a surface-film or submerged-strewn egg breeder? 



2. After the discovery (1922) of R. heckscheri young tadpoles, greater 

 refinement of H. cinerea description is needed. Few H. cinerea tad- 

 poles found in 1922. 



3. More transformations are needed. 



4. Rate of growth problematic in intermediate sizes until more material 

 appears. 



5. Study transformed green tree frogs of H. andersonii, H. cinerea, H. c. 

 eviiiata, H. squirella, and H. gratiosa for clues to relationships when 

 they begin to assume their adult patterns. 



Hyla femoralis 



1. This common Sabalian form could be used for cross breeding experi- 

 ments and possibly hybridization with other Hylas. 



2. The larval period needs to be better determined. 



3. This denizen of the high long leaved pines would be a good subject for 

 food studies. It would yield interesting material of the upper levels 

 of the pine barrens. 



4. Abnormal variations in its tadpoles might be interesting to follow. 

 Hyla gratiosa 



1 . What is the post and pre-breeding habits of this species? 



2. Why two dissimilar calls in this species? 



3. Egg-laying process in laboratory and in field needs to be watched. 



4. Intermediate sizes from 25-50 mm. are badly needed in collections for 

 growth studies. 



Hyla squirella 



I . Why is this Hyla more of a house treef rog or found more about human 

 quarters, habitations, barns, cultivated yards, etc.?
