Genus DIAGLENA Cope 



1887. Diaglena Cope, U. S. Nat. Mus. Bull. 32, p. 12. [Genotype, Diaglena 

 spatulata (Gunther) = Triprion spatulatus Gunther, 1882, Ann. and Mag. 

 Nat. Hist., ser. 5, vol. 10, no. 58, p. 279, Oct. (Presidio, Sinaloa, Mexico).] 



This monotypical genus is characterized in part by the presence of 

 palatine teeth and also by pecuharities in the conformation of the bony 

 casque.

1882. Triprion spatulatus Gunther, Ann. and Mag. Nat. Hist., ser. 5, vol. 10, 

 no. 58, p. 279, Oct. — Boulenger, 1891, Ann. and Mag. Nat. Hist., ser. 6, 

 vol. 8, no. 48, p. 456, Dec. — Gunther, 1901, Biologia Centrali-Americana,

Type locality. — Presidio, 50 miles from Mazatlan, State of Sinaloa, 

 Mexico. 



Range. — Exact limits of range problematical; thus far known to 

 occur only in southern Sinaloa. 



Remarks. — The three cotypes of this species were collected by Dr. 

 Alphonso Forrer. The follo^^dng notes were made on these specimens: 

 Vomerine teeth behind but within level of inner margins of choanae; 

 they vary in position from transverse to a broad open inverted V; no 

 tarsal fold; large internal metatarsal tubercles; the hind limb being 

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

 of tympanum; fingers not webbed at base; tip of first finger reaches to 

 apical disk of second; coloration as described by Boulenger. 



B.M. No. 82. 11. 13. 1, one cotype: Head-and-body length, 86 mm.; 

 transverse diameter of tjmipanum, 3.9 mm.; transverse diameter of 

 eye, 7.2 mm.; posterior margin of bony casque to tip of snout, 30.2 

 mm.; width of head at level of posterior angles of jaws, 24.4 mm.; tip 

 of snout spinose.
