the rings there, and there are some intermediate striae. The latter 

 are very rare indeed among the older rings." 



Salter's specimens were procured from Warm Bokkeveld and 

 Hottentot's Kloof. 



Affinities. — This species is allied to T. bellulus, Hall," which has 

 been recorded from the Devonian of Bolivia,! and from Matto 

 Grosso,! but the finer striae between the rings are generally absent or 

 faint in the Cape species, though this may be largely due to the 

 state of preservation. Kayser S has recorded a similar or identical 

 form from Argentina. 



Localities. — (No. 132) Kloof north-west of homestead on Laken 

 Vley, Ceres; and Warm Bokkeveld (type). 



TENTACULITES BAINI sp. nov. 

 (PI. XXX., fig. 9.) 



There is one slightly crushed specimen (No. 181) of a species of 

 Tcntaciilites which is certainly distinct from T. crotalinus and 

 appears to be new. The shell is straight, conical, pointed, tapering 

 rather rapidly to the apex at the rate of about 1 in 5. It i& 

 annulated with a very few widely-separated weak rings, which are 

 grooved and placed at regular intervals equal to about two-thirds the 

 local diameter of the shell. In the present specimen there are only 

 six rings visible along the whole length, but the apical portion is not 

 well preserved. The interspaces are broad, and apparently marked 

 by fine concentric and faint longitudinal striae. 



Dimensions. — Length 35 mm. ; diameter near mouth 8 mm. 



Affinities. — The distinguishing feature is the wide distance apai't 

 of the rings and their small number. In this respect it resembles 

 T. eldredgianus, Hartt and Eathbun,[| from the Devonian of the 

 Lower Amazon. 



Locality. — (No. 181) Gydo Pass, Ceres.
