Type locality. —Pacific region of the Isthmus of Tehuan tepee, 

 Mexico. 



Range. — Central Vera Cruz southward through the Isthmus of 

 Tehaantepec to San Salvador. 



Remarks. — The type of Hylodes berkenbuschii (M.N.B. No. 6666) 

 has been examined, independently, by Dr. E. R. Dunn and myself, 

 and both of us agree that it is identical with Cope's Liyla rugulosa. 

 The folloAving notes were made on this specimen : 



Head-and-body length, 42.5 mm.; transverse diameter of tym- 

 panum, 3.9 mm.; transverse diameter of eye, 5.8 mm.; the hind limb 

 being carried forward along the body, the tibio-tarsal joint reaches to 

 end of snout; web at base of toes extends to or a little beyond proximal 

 subarticular tubercle; tarsal fold sharp and quite distinct; inner meta- 

 tarsal tubercle quite large, outer tubercle minute; no sapernumerary 

 tubercles on plantar surface of foot; apical disks of toes smaller than 

 those of fingers; canthus rostralis sharp; loreal region oblique; tym- 

 panum overhung by dermal fold; sldn of upperparts rather rough, 

 with a pair of oblique dermal plicae on each shoulder and a linear 

 series of short interrupted glandular ridges along sides of back; skin 

 of abdomen areolate; under surface of thighs areolate, with a few 

 warts below vent; upperparts brown; a dark interorbital transverse 

 band, in front of which the top of the head is suffused with white, 

 extends laterally upon posterior edges of upper eyelids; narrow vertical 

 light yellow stripes on upper lip alternating with subtriangular dark 

 spots; dark stripe above and downward behind tympanum; sides of 

 body mottled with a darker color; hind limbs with indistinct dark 

 cross bands; a narrow wliite throat line; underparts brownish yellow, 

 with darker mottling; posterior surfaces of thighs with small white 

 spots. 



The two cotypes of Liyla rugulosa (U.S.N.M. Nos. 29771-72) 

 mentioned by Cope are now poorly preserved and rather soft. Por- 

 tions of both specimens are bleached nearly white, and the color 

 marldngs are obliterated. The skin of the upperparts is somewhat 

 wrinkled, but the dermal glandular ridges are still visible. One of 

 the cotypes (U.S.N.M. No. 29772) has the sldn freed from the head, 

 the sternum dissected out, and the extremity of the right sacral 

 diapophysis exposed. This specimen has a head-and-body length of 

 33 mm., while the other cotype measures 36 mm. in length. A large
