42 Ammonoidea from Pondoland 



the ornamentation is the same, with very fine striation, strongly 

 drawn forward on the umbilical slope, but straight on the sides and 

 across the periphery, with occasional varices on the cast, and ridges 

 on the shell. The latter are not nearly so conspicuous as those of the 

 New Zealand form figured by Woods. 1 The Japanese example figured 

 by Jim bo 2 agrees with the present form in fatness and coiling, but has 

 the striation drawn forward laterally and ventrally as well, a feature 

 that suggests that Jimbo's form is more nearly allied to G. tenuiliratum, 

 Yabe, or to G. cinctum, Crick MS. 



The Cenomanian example of G. aff. sacya, recorded from Zululand 

 by Crick 3 apparently differs very little from the form here described, 

 but increases less rapidly in whorl-thickness. The suture-lines, 

 unfortunately, cannot be compared, Crick's type (B.M. No. CI 8 140) 

 being corroded. 



Genus TETRAGONITES, Kossmat.

[Cf. 1895. Lytoceras (Tetragonites) epigonum, Kossmat, loc. cit. p. 

 135, pi. XVII, fig. 5]. 



The immature example, here figured, seems to agree with Kossmat's 

 small specimen, but since it is crushed, and the width of the umbilicus 

 thus is deceptive, the specimen also may be a young Pseudophyllites, 

 comparable with Forbes' A. garuda (B.M. No. 10462, Geol. Soc. Coll.). 



An example from Pondoland, referred to Kossmat's form by 

 Mr. Crick, is in the British Museum (No. CI 94 16) and though more 

 definitely identifiable as a Tetragonites, it is only fragmentary. 



T. teres, van Hoopen 4 which greatly resembles specimens of Pseudo- 

 phyllites from Pondoland and from India, has a very high outer whorl, 

 whereas in Kossmat's form, the whorl-height is just a trifle less than
