This species occurs throughout Tamaulipas. A female from Soto la
Marina, obtained on May 17, was lactating; another from 12 miles
northwest of San Carlos, on August 23, carried two embryos that were 15
mm. in crown-rump length.

=Sylvilagus floridanus connectens= (Nelson)
1904. _Lepus floridanus connectens_ Nelson, Proc. Biol. Soc.
Washington, 17:105, May 18, type from Chichicaxtle,
Veracruz.

Bull. U. S. Nat. Mus., 62:32, January 28.
_Distribution in Tamaulipas._--Southern part of state.
This subspecies has been reported previously from Tamaulipas only from
Altamira. Specimens from 10 kilometers north and eight kilometers west
of El Encino and 70 kilometers south of Ciudad Victoria, judging by
their large size, dark color, and ochraceous brown (rather than pale
ochraceous as in _S. f. chapmani_) upper sides of the hind feet are
assignable to _connectens_.
Goodwin (1954:7) reported specimens from Chamal, Joya de Salas, Gomez
Farias, and Pano Ayuctle as _S. f. chapmani_, remarking that they were
intergrades between _chapmani_ and _connectens_. Specimens reported by
Goodwin are here assigned to _S. f. connectens_ because the
measurements of the specimen from eight kilometers west of El Encino
are typical of that subspecies.
_Records of occurrence._--Specimens examined, 4: 10 km. N, 8
km. W El Encino, 400 ft., 1; 2 km. W El Carrizo, 2; 9 mi. SW
Tula, 5200 ft., 1.
Additional records (Goodwin, 1954:7, unless otherwise
noted): Chamal; La Joya de Salas; Gomez Farias; Rancho Pano
Ayuctle; Altamira (Nelson, 1909:186).
