37008. Slab of lithographic limestone, showing the skeleton with 

 the exception of the greater portion of the tail ; from the 

 Kimeridgian of Solenhofen, Bavaria. The dorsal surface 

 is shown. The skull is much crushed ; and the right ramus 

 of the mandible is thrust up so as to exhibit its dentition. 

 The pectoral limbs are well preserved; but the pelvic 

 girdle and limbs have been broken up by a fracture through 

 the sacral region. This specimen agrees so well with the 

 type example (including the hinder portion of the trunk, 

 the left hind limb, and the anterior moiety of the tail) 

 figured by Meyer in his ' Fauna der Vorwelt — Rept. Lith. 

 Schiefer/ pi. xiv. fig. 1, that there can be but little hesita- 

 tion in referring it to that form ; the short phalangeals of 

 the pes being, although heaped in a confused mass, clearly 

 apparent in the present specimen. It is, however, very 

 difficult to see how the specimen differs from the imper- 

 fect skeleton of Anguisaurns represented in fig. 2 of the 

 same plate. Meyer, indeed, states that the anterior caudal 

 vertebrae of the latter are more slender than those of 

 Pleurosaurus ; but the different position in which these 

 vertebrae are placed in the type specimens and their 

 damaged condition in that of the last-named genus, renders 

 any deductions drawn from this part of the skeleton very 

 unreliable. The skull resembles very closely that of the 

 type specimen of the small Acrosaurus fischmanni figured 

 by Meyer, op. cit. pi. xii. fig. 6 ; but has a length of 0,010. 

 The lower teeth are acrodont ; and have low, compressed, 

 lancet-shaped crowns, which are widely separated from 

 one another, and may have had longitudinally expanded 

 bases like those of Acrosaurus {op. cit. figs. 7-8).

Family TELERPETID^E. 



In the type genus, according to Huxley, no postorbital bar in 

 the skull ; tusk-like teeth in the premaxilla and mandible ; and 

 only two phalangeals in the fifth digit of the pes. Huxley restores 

 the skull with only one temporal arcade; and abdominal ribs have 

 not been observed. The serial position is provisional.
