On Cretaceous Cephalopoda from Zululand. 289 1 



A small fragment (No. 4982) of a completely septate, free and 

 unsymmetrical whorl resembles the above form in size, coiling and 

 quadrituberculation, but the costae are broader and all equal. The 

 tubercles are less prominent, agreeing in this respect with those of 

 Anisoceras pseudopunctatum, Pictet & Campiche,* and the costae 

 are slightly weakened between the ventral tubercles, but flattened, 

 after the manner of those of A. perarmatum, Pictet & Campiche.t 

 between the ventral and lateral tubercles. 



" Helicoceras " astierianum, d'Orbigny in Parona and Bonarelli,^ 

 shows only slightly closer coiling than the present form, and other 

 comparable forms, e. g. Turrilites eleyans, Pictet & Campiche, pars, 

 non d'Orbigny, have somewhat similar ornamentation. It appears 

 most probable, however, that the example here recorded represents 

 part of the helicoid initial whorls of an Anisoceras of the typical 

 group of A. saussureanuiH . Pictet, || and A. ohlhainian>im, Stoliczka.^f 

 The suture-line differs from that of the typical Anisoceras in the wide 

 external saddle, and from those equally simple ones of certain Hamitids 

 (Toriietttoceras) in the unsymmetrical first lateral lobe (PI. XXVI, 

 fig. 7). 



Locality. Low Ridge, about three miles east of foot of Lebombo 

 Mountains, north of M'Kusi River, due east of Ubombo. Coll. 

 W. J. Wybergh. This is the only specimen in the present collection 

 from this locality, further north than that of any of the other (post- 

 Aptian) Cephalopoda ; but the facies appears to be the same as that 

 of the Albian Manuan Creek fauna.

 A small portion of a Tiirrilites (No. 4954) , with five rows of tubercles, 

 agrees with the example from Madagascar, in having the upper two 

 tubercles very close together. Since these coincide with the upper
