Hab. Mozambique (Gibbons). 



When Pollonera created a new genus for the slug which Gibbons mis- 

 identified as Urocyclus flavescens Kfstn., he retained the name flavescens 

 for the species, merely transferring its authorship to Gibbons, on the ground 

 that, as it now belongs to a different genus, the name is valid. As, however, 

 Gibbons described the species as an Urocyclus, Pollonera's action is con- 

 trary to the rules of nomenclature, and a new name is required for his 

 genotype. It may be suggested that Gibbons' own name of pallida should 

 be applied to the species, of which, in that case, his U. flavescens would 

 become a darker coloured variety, but as it is the radula of the latter that 

 has been published, and there is no certainty that pallida is even conspecific, 

 it seems wiser to adopt my procedure. 



Family ENDODONTIDAE. 



Subfamily ENDODONTINAE.

Hab. L. Marques. Mt. Vengo, 5500 ft. (Cressy). 



This species had only been collected previously in the Cape Province, 

 but I am now able to record a locality in Natal, Ntimbankulu (Burnup). 



Some notes on the anatomy follow : — 



The foot has well-marked peripodial grooves, and is of a light colour. 

 The tentacles are nearly black, and show clearly through the overlying 

 tissues when they are contracted. The roof of the mantle-cavity is pale 

 and translucent. 



The kidney (text-fig. 9, A) is rather broad and about twice the length of 

 the pericardium. It extends a little further back than usual, and the posterior 

 part stretches upwards to the rectum, though the upper prolongation between 

 the rectum and the secondary ureter is not developed in this species as it is 

 in Track, pur a Conn. The ureter arises from the front end of the kidney 

 and is reflexed in the usual manner. 



The jaw measures about 1-1 X -IS mm. It is very thin, and is crossed 

 by about twelve narrow vertical folds. 



The radula (text-fig. 9, B) measures •38x-l mm. when flattened out.
