ICTIDOPSIS FORMOSA, sp. n. 
THREE specimens of this species are now in onr collection. Two have 
been found, one by myself and one by my assistant, in James’ donga, 
Harrismith. The third also comes from Harrismith, but the exact locality 
is unknown. The new species is larger than the type species, and its 
interorbital space is relatively broader. The hinder end of the nasal is 
only slightly broader than the front end.

Glochinodon detinens, gen. et sp. n. 
This new genus is founded on a badly preserved skull with a small 
portion of the postcranial skeleton. It was found by myself at Harrismith 
in a small side-gully of James’ donga, to the north of the brickworks and 
exactly south of the small municipal installation for crushing road-metal. 
Molars : In right maxillary eight large ones ; in left maxillary 
eight large ones and a small one between the seventh and ninth. One 
canine in each maxillary and one in each ramus of the lower jaw. The 
upper incisors are lost ; in the lower jaw there are traces of two incisors 
in each ramus. Dental formula probably : i. : \ ; c. : \ ; m. : The 
molars have two cusps. The hinder cusp is small and directs its point 
forward. The front cusp is large and bends backwards over the point 
of the hinder cusp and so that its outer edge stands at right angles with 
the front of the tooth. Length of the skull : Less than 65 mm.
