70 CRITICAL REMARKS ON TABLE CAPE FOSSIL MOLLUSCA 



by several additional figures. I have also' taken the 

 opportunity of fignring tiwo of Tenisom-Woods' types 

 from the Museum collection. In the following critical 

 remarks, I deal not only with the species figured, but 

 also with s:ome that appear to be synonyms or unrecognis- 

 able. 



In all cases I give the author's original generic names. 



Emarginula transenna, Tenison-Woodsi. 



From a Johnston co-typ'e, which measures 8 mm. high 

 and 12 X 8 mm. in diameter. A, noteworthy feature not 

 mentioned by the author is that the slit is situated in a 

 strong rib. (Plate VIII., fig. 1). 



Gihhula clarkei, Tenision-Woods. 



The type lot in thei Johnston collection contains a 

 number of specimens of various^ sizes; they vary much 

 from each other in the strength of the spiral ornament. 



I have selected one of the^ most perfect for figuring, which 

 measures 3x5 mm. in dia.meter, and it may stand as the 

 type. (Plate VIII., fig. 2). 



Gibhula ceqinsulcata, Tenison-Woods. 



From a Johnston co-type, measuring 11 mm. wide and 

 9 mm. high. (Plate VIII., fig. 3.) 



Gibhula crassigranosa, Tenison-Woods. 



From a Johnston oo-type (or possibly type) measuring 



II mm. in diameter and 12 mm. high. From a compari- 

 son with the type, and another in the Johnston collection 

 of Astralium (Calcar) ornatissimum, T'enison- Woods, this 

 would seem, to be scarcely distinct; in the former the 

 nodulesi have developed into short spines, but there seemsi 

 otherwise no appreciable difference. (Plate VIII., fig. 4). 



Solarium (Torinia) gibhuloides, Tenison-Woods. 



From one of Johnston's co-tvpes. (Plate VIII., 

 fig. 5). 



Deljohinula tetragonostoma, Tenison-Woods. 



Johnston's two specimens are probably the tyjoe, and 

 a co-type. They show the species to be an undoubted 

 Crossea, and a beaiutiful addition to that interesting genus. 

 As neither of these specimensi waiS in a sufficiently perfect 

 state of preservation to make a good figure, I have drawn 

 it from one of my own compared with the above. (Plate 

 IX., fig. 6).
