LEPTODEIRA FRENATA (Cope) 



Leptodeira frenata Smith, Proc. Biol. Soc. Washington, vol. 52, pp. 192-195, fig. 8, 

 1939. 



Three specimens (Nos. 111193-4, HMS No. 3771) are from Palma 

 Sola. Veracruz. They were found in bromelias in the dry season. 



This forms shows a great similarity to y. yucatanensis, even to the 

 paired parietal spots and the fusion of the postocular stripe with the 

 first dorsal blotch. 



The Museum has no others of the species. 



LEPTODEIRA MACULATA (Hallowell) 



Twenty-six specimens were secured, as follows: Chiapas: Tonala 

 (Nos. 111216-8). Guerrero: Acapulco (No. 111201); Coyuca (Nos. 

 111202-3) ; Tierra Colorado (Nos. 111204-5) ; Agua del Obispo (No. 

 111206). Oaxaca: Cerro Arenal (No. 111214); Tehuantepec (Nos. 

 111207-13); Cerro Guengola (No. 111215). San Luis Potosi: 

 Huichihuayan (Nos. 111219-20). Veracruz: Potrero Viejo (Nos. 

 111195-7) ; Palma Sola (Nos. 111198-200). Some were found in bro- 

 melias, others under bark on trees, others at night in arroyos. 



One (No. 111208) from Tehuantepec agrees with the dark color 

 phase described by Taylor (1939a, p. 339, pi. 32, fig. 1). The suprala- 

 bials are uniformly 8-8; preoculars 1-1 in one, 1-2 in two, 2-3 in one, 

 and 2-2 in the remainder, postoculars 2-2 in all; and temporals 1-2-3 

 in all except two, which have four posterior temporals. Other details 

 of variation are given in table 20. 



The Museum has 40 other specimens, all from Mexico except per- 

 haps the type (No. 7367) , which presumably is from Nicaragua. They 

 are as follows: Colima: Orolata (No. 56344); Colima (Nos. 31426, 

 31485-90). Guerrero: Acapulco (No. 46403); Coyuca (No. 46344). 

 Jalisco: Guadalajara (No. 24962); Miramar (Nos. 51471-7); San 

 Bias (No. 51478). Oaxaca: Zanatepec (No. 46498) ; Santa Efigenia 

 ( No. 46497 ) ; Tehuantepec ( Nos. 30306-7, 30480 ) . Sinaloa : Mazathin 

 (No. 6836); Kosario (No. 62201). Veracruz: Orizaba (Nos. 6324, 

 7095) ; hills west of Veracruz (No. 5317) ; Mirador (Nos. 6373, 25040, 

 61990-2); Tuxpan (No. 25208). Indefinite: "Mexico" (Nos. 11378, 

 16389, 32169) ; "Cape St. Lucas" (No. 11290). 



Mus. Comp. Zool. No. 11420, from "Colima" (Gluckert), has the 

 fewest body spots (17-18) of any recorded in macvlata, closely ap- 

 proaching xin if hi in this respect. Another (No. 11419) with the same 

 locality data has 21-22 body spots, a number within the previously 

 known range of the species.
