Amphibia of the Claremont-Laguna Region 



(Preliminary List) 



Three species of Urodela have been found in this region, 



Batrachoscps atteniiatus Esch. This very slender species has 

 been found more widely distributed than any other in this region. 

 It is most easily found during wet years. Individuals have been 

 collecteci during the past two years from well up in the mountains 

 in Cow canyon, one of the branches of the San Gabriel. They have 

 been found abundantly in and about Claremont. Some were col- 

 lected on top of the highest hills near Laguna, as well as in one of 

 the smaller canyons less than a mile from the sea. A number of 

 specimens were also obtained from Catalina Island. 



Aiitodax lugnhris Hallow. So far this species, or animals resem- 

 bling it, have been obtained from the mountains. It has not been 

 found abundantly. Only some of the lower canyons which are 

 rather rocky have furnished specimens, such as Stoddard's and 

 Cucamonga. 



Dicmyctylus torosus Esch. This large aquatic salamander is 

 found in many of the larger canyons and in water which flows from 

 mountain streams. We have found it most abundantly in San 

 Dimas, Cucamonga, Live Oak, Big Dalton and Palmer's. It prob- 

 ably occurs in many others. 



We have but five species of Anura so far: 



Riifo halophiliis Baird. Common in all the region from the 

 mountains to the sea. 



Hyla arenicolor Cope. Gray or brown spotted or blotched or 

 unspotted. Found in the canyons. 



Hyla regalia Baird and Girard. These little frogs, gray, brown, 

 green or red are probably found in all the region. They have been 

 found breeding this year in February among the hills near Pomona. 

 They were found very abundantly among the tall vegetation about 

 the lakes near Laguna Beach. 



Rana pretriosa Baird and Girard. This frog is found in most 

 of the larger streams in the mountains. 



Rana draytouii Baird and Girard. One specimen of this large 

 frog was brought in from San Dimas canyon in 1914.
