MEXICAN HERPETOLOGICAL MISCELLANY—SMITH 357 
ity of Puebla, Puebla, in the American Museum of Natural History. 
Diagnosis—Similar to m. mucronatus, except: Dorsal scales usually 
more than 32; femoral pores usually over 13; no parallel longitudinal 
dark lines on middle of throat; adult males usually with longitudinal 
dark lines following the edges of the dorsal scale rows; centers of 
scales light; collar involving not over 4 scale lengths longitudinally. 
Remarks.—1 described this subspecies in detail’ as mucronatus 
omiltemanus. The latter name, however, must be restricted to the 
larger scaled, broad-collared form lacking longitudinal dark lines 
following the dorsal scale rows, that occurs in the isolated mountain 
range of central Guerrero. 
Comparisons.—S.m. aureolus is amply well differentiated from both 
mucronatus mucronatus and m. omiltemanus by having more nu- 
merous dorsals (30 to 38, average 34.3, 91.6 percent over 31 in 59 
aureolus; 27 to 32, average 29.6, 93.6 percent 31 or less in 49 mucro- 
natus ; 29 to 82, average 30, 92.3 percent less than 32 in omiltemanus), 
and a lined dorsal pattern in adult males. From m. mucronatus it 
also differs in average femoral pore count (11 to 17, average 14, in 
124 counts of awreolus; 10 to 17, average 12.8, in 94 counts of mucro- 
natus; 11 to 16, average 13.8, in 26 counts of oméltemanus) and in 
lacking the parallel, longitudinal dark lines on the throat (present 
in all except adult male mucronatus, lacking in omiltemanus). It is 
apparent that m. mucronatus and m. omiltemanus are more like each 
other than either is like aureolus. They differ from each other in 
dorsal pattern; omdltemanus lacks the large dorsal blotches and the 
parallel, longitudinal dark lines on the throat of mucronatus, and in 
addition has a collar involving at least 414 scale lengths (4 or less 
in mucronatus). 
SCELOPORUS JARROVII SUGILLATUS, new subspecies 
Holotype.—U.S.N.M. No. 112100, male, from the edge of the east 
end of Lake No. 4, Zempoala, Mexico, Mexico.® 
Paratypes.—F ifty-four, all topotypes, including U.S.N.M. Nos. 
112072-112099, 112101-112111, and EHT-HMS Nos. 22311-22321. 
Diagnosis —Supraoculars in 2 rows; dorsal scales 37 to 44, average 
40.6; median lateral body scales distinctly smaller than middorsal 
scales; scales on dorsal surface of upper foreleg about twice as large 
as those on lower foreleg; gray or blue-gray above, streaked, with a 
rather broad, black nuchal collar (6 to 8 scales wide) ; sides of belly 
slate blue, not black-edged, with vertical streaks of black; chin light 
blue; males and females practically indistinguishable in ventral color.

Park of Zempoala. Most of the park is in the State of Mexico.
