very closely rugosely punctured, tlie postscutellum more 

 sparsely punctured ; pronotura about two-thirds as long; as 

 the scutellum. Median segment rugosely punctured; the 

 basal area triangular, almost equilateral, obliquely striated, 

 with a median longitudinal groove, the apex irregularly 

 transversely striated. Tergites strongly but not closely 

 puuctured, first tergite broader at the apex than long ; 

 pygidial area rugulose, elongate, fully twice as long as its 

 greatest breadth, and more than three times as long as its 

 apical breadth, the apex subtruncate. Second sternite 

 shining-, sparsely punctured.

This belongs to the group of the European C. labiata, 

 and is rather closely related to that species, but is not 

 very near any other Ethiopian species. The interantennal 

 carina is less elevated than in labiata, and is flattened to- 

 wards the base of the elvpeus. Two females from Mlanje 

 Plateau, Nyasaland, 6500 ft. [S. A.Neave), December 191?, 

 have the postscutellum black and the lamina of the clypeus 

 much reduced in size. These may represent a subspecies, 

 but I cannot regard them as specifically distinct.

Thecodontosaurus minor, sp. n. 



The specimens forming the type of this new form were 

 presented to the South African Museum by the late Dr. I\l. 

 RicoiiQ. They consist of a left tibia, a cervical vertebra, 

 and a portion of the left ilium. 



Left Tibia. — The tibia is 109 mm. long. The proximal 

 articular surface is 31 mm. long and 18 mm. broad. This 

 surface for ihe most part slopes obliquely backwards and 

 late! ally, the inner border being convex from front to back 

 and higher in front than behind. The tuberositas tibiae is 

 almost tlie highest point of the bone; it is prolonged ante- 

 riorly and turned slightly outwards. The lateral condyle is
