NO. 1156. VAniATlONS OF HTLA hegilla—test. 479 



Immediately following this description' is one of Ryla scapularis vskv. 

 hypochondriaea. This is said to be — 



Of a uniform pale olive color above, without spots, paler toward the sides; num- 

 erous small, el<■vat(^d, smooth points upon the surface, resembling tubercles; upper 

 surface of extremities pale olive; a narrow, dark colored vitta extending from the 

 anterior margin of the eye to the snout, another much broader from the j>osterior 

 margin of the eye to the shoulder; margin of upper jaw of same color as the vitta; 

 posterior part of abdomen and under surface of extremities orange colored; chin 

 and throat white; abdomen thickly granulated. It will be observed that it wants 

 the sfjualus tooth-like mark upon the head and the; markings upon the back which 

 belong to avapularifi. 



These specimens also are in the Museum collection as ^o. 3235, 

 Tejon Pass, California, Dr. A. L. Heermaun, and a careful examination 

 of them shows that two of the nine specimens do possess the squalus 

 spot on the head, denied them in the original description, but it is very 

 dim and indistinct, and there are also fiiint indications of dorsal stripes. 



In 186C, owing to the preoccupation of the name nehiilosn by a species 

 of hyla described by Spix, Cope renamed Uallo well's specimens Hyla 

 eadaverina.^ As said above, one of the specimens is in the U. S. 

 National Museum collection. 



The same year' Cope described Jlyla rwrfa, collected at Cape St. 

 Lucas, Lower California, by John Xantus. This is a stout form, with — 



size small, bn-adth of jaws entering total length two and two-thirds times. Males 

 without gular vocal vehicle. Femur posteriorly unicolor, basal fold weak, a ilark 

 labial liorder and band from nostril to axilla, above ashy brown, with a dark inter- 

 ocular triangle and a broad dor.so-latcral band on each side, often broken into elon- 

 gate spots. Limbs pMn<tulate and cross barred. * * * The groin is sometimes 

 mottled with black, and the sides often with brown or marbled, which may extend 

 over the iliac region. .Simietimes all the dark markings are marbled with paler. 

 There is a band on the front of the humerus, and the hind limbs are freciuently 

 double banded. 



These are in the Museum collection as No. 5293, nineteen specimens, 

 and an examination leads to the belief that a small vocal sac does exist, 

 as the throats of two or three of the males are slightly wrinkled, and 

 that the api^arent absence is partly due to the si)ecimens being young, 

 few of them being over an inch in length, and partly to their having 

 been collected out of the breeding season. 



In his "liatrachia of North America"* Cope gathered all the Pacific 

 Hylas together as Hyla re<jilla, with the three varieties, regilla proper, 

 scapuJaris, and laticeps. Laticeps he describes from eleven specimens 

 from Cape St. Lucas (No. 5308, U.S.N.M.), collected by Xantus, but 

 the description is very incomplete and confused from being mixed up 

 with one of curta, which he seems uncertain whether to merge with the 

 variety regilla or still keep separate. The three specimens of scapidaris,
