The specimens from 18 kilometers east of Dos Aguas were found on July
22, 1960, by Floyd L. Downs and John Winklemann, who collected calling
males of _Tomodactylus rufescens_ and _Tomodactylus nitidus petersi_ at
the same locality. Downs (_personal communication_) stated the call was
a single note. At Dos Aguas I heard _T. rufescens_ give two calls, one a
single "peep," the other a triple note--"pee-ee-eep."

In the higher parts of the Sierra de Coalcoman _Tomodactylus rufescens_
seems to fill the same niche as _T. angustidigitorum_ does in the
Cordillera Volcanica. At lower elevations in their respective mountain
ranges the species occur sympatrically with _T. nitidus petersi_.

~Diaglena reticulata~ Taylor

Nueva Italia (3); Ostula (7).

Until recently frogs of the genus _Diaglena_ were known only from a few
specimens from southern Sinaloa (_Diaglena spatulata_) and from the
Pacific lowlands of the Isthmus of Tehuantepec (_Diaglena reticulata_).
Peters (1955a) reported specimens from Ostula, Michoacan, and compared
these specimens with one _D. reticulata_ from Tehuantepec, Oaxaca, and
four _D. spatulata_ from Sinaloa. This comparison showed that the
specimens from Michoacan, although showing some minor differences from
_D. reticulata_, are closer to that species than to _D. spatulata_.
Subsequent to Peters' work, series of both species of _Diaglena_,
including additional specimens from Michoacan and from Colima, have been
collected, and a more qualified comparison is now possible.

In comparing specimens of _D. spatulata_ from southern Sinaloa (UMMZ
115322) with specimens of _D. reticulata_ from Tehuantepec, Oaxaca (UMMZ
115321), the differences noted by Taylor (1942c:60) were found to be
constant. But specimens from Ostula, Michoacan (UMMZ 104418), and five
individuals from Colima (TNHC 26379-83) were found to be intermediate in
certain characters. The skin of the dorsum in _D. reticulata_ is
granular; that in _D. spatulata_ is smooth. The skin in specimens from
Ostula and Colima is slightly granular. The dorsal ground color of _D.
reticulata_ is yellowish brown with dark reticulations; the dorsal
ground color of _D. spatulata_ is olive-green. Specimens from Ostula and
Colima most closely resemble those from Tehuantepec in coloration, but
the reticulations are more coarse,
