. Breviora. . Figure 3. Holotype of Latjosiichus talampaynisis. A, Tibia, fibula, and pes; B, femur and incomplete tibia and fibula; C, incomplete humerus, radius, and ulna. X +/3. metatarsals 1-4 are, in order: 38-39, 47-48, 15, 23, 26, and 25 mm. In the type only a few phalanges are preserved, but it was obx'ious from the metapodial lengths that digit 4 would ha\e been slightly shorter than digit 3; metapodial 1, it will be noted, is relati\'ely longer than in Lagerpeton. The foot restora- tion given in Figure 2 of my earlier paper (1971) was com- pleted from the problematical Instituto Lill

The foot restora- tion given in Figure 2 of my earlier paper (1971) was com- pleted from the problematical Instituto Lillo specimen discussed below. Vertebrae present on this slab, which I pre\'iously thought pertained to this form, appear on closer study to be caudals of Gracilisuchus. MCZ 4116 is a slab on which are numerous bones of Gracilisuchus. At one corner, however, are a few remains of Lagosuchus. These include: a femur 37 mm long closely re- sembling the type, articulated with which is the proximal end of a tibia: a series of dorsal vertebrae (Fig. 4) ; fragmentary remains of the pehis. The vertebrae have central lengths of slightly over 5 mm. In the Tucuman collections there is a hind leg that corresponds closely with the type in pattern. Measurements of femur, tibia,.
