The small K. (Madrasites) cf. madrasinum, Stoliczka sp., figured as 

 Holcodiscus sp. by Woods, t from Poudoland, is distinguished by its 

 pronounced umbilical tuberculatiou. The Madagascar form of Koss- 

 maticeras (Madrasites) figured by Boule, Lemoine and Tlu'veuinJ as 

 " Holcodiscus theobaldinus, Stoliczka sp. var.," differs from the form 

 here described in having a larger umbilicus. 



Crick described (in MS.) two species of Kossmaticeras from Pondo- 

 land as Holcodiscus natalensis and H. acuticostatus. He did not 

 compare them with Woods' form, which is more involute, but stated 

 that their nearest ally appeared to be H. buddhaicus, Kossinat a 

 statement with which the writer agrees. These two forms (B.M., 

 No. C19432-3) differ little from each other, but are distinguished 

 from the species here described by being evolute (U = 34 per cent, 

 and 37 per cent, respectively) and by having umbilical tubercles 

 throughout. K. (Madrasites) faku and K. (M.) africanum, Hoepeu 

 sp., are closely similar forms represented in the collection from the 

 Durban Museum. 



Kiliau has recorded K. bhavani also from New Caledonia, || and 

 related forms occur throughout the Indo-Pacific province, whereas the 

 European forms recorded as Kossmaticeras belong to other groups 

 than the finely -ribbed South African Madrasites.
