Fig. 20 in Observations on Garter Snakes of the Thamnophis eques Complex in the Lakes of Mexico's Transvolcanic Belt, with Descriptions of New Taxa

Fig. 20. Upper. Two young dark examples of Thamnophis eques carmenensis from near El Carmen, Tlaxcala. Lengths 686 mm left, 562 mm right. Smaller members of this taxon frequently hid their heads beneath their bodies. Lower. Nearly white venter of a female 700 mm in length from the same locality. All collected July 8, 1964.

Fig. 17 in Observations on Garter Snakes of the Thamnophis eques Complex in the Lakes of Mexico's Transvolcanic Belt, with Descriptions of New Taxa

Fig. 17. From the former Lago de Magdalena, Jalisco. Upper. A male of Thamnophis eques scotti, 953 mm in length, collected August 30, 1961. The middorsal stripe is variable in width but not sharply defined from the ground color between the lateral dark spots. Lower. Venter of gravid female, same locality and date, length 1009 mm. Belly pale.

Fig. 16 in Observations on Garter Snakes of the Thamnophis eques Complex in the Lakes of Mexico's Transvolcanic Belt, with Descriptions of New Taxa

Fig. 16. The Lago de Magdalena, Jalisco, when it was considerably larger and extended to La Quemada. Adapted by W.H. Brandenburg from Mexican CETENAL topographic maps of 1973 showing low flat areas that at one time were presumably occupied by the lake.

Fig. 15 in Observations on Garter Snakes of the Thamnophis eques Complex in the Lakes of Mexico's Transvolcanic Belt, with Descriptions of New Taxa

Fig. 15. The ledge near Magdalena, Jalisco, where we observed about 50 large Thamnophis eques scotti assembled in a balllike mass at night. Water flowed across the ledge after heavy rains and a crude bridge passed over it.

Fig. 13 in Observations on Garter Snakes of the Thamnophis eques Complex in the Lakes of Mexico's Transvolcanic Belt, with Descriptions of New Taxa

Fig. 13. From the Laguna de Cajititlán, Jalisco. Upper. A female Thamnophis eques diluvialis, 1055 mm in length, collected July 29, 1965. Lower. A male, AMNH 91692, 900 mm in length, from an isolated locality west of Ixtlahuacán de los Membrillos, Jalisco, collected July 10, 1959. Because of the angle at which the photographs of the two snakes were taken, the pale middorsal stripe is less conspicuous than it was in life.
