cannot follow Professor Haddon (Trans. Roy. Dubl. Soc. 

 ser. 2, vol. iv. p. 321) in regarding Tealia tuberculata as a 

 possible synonym of Actinauge Richardi. Owing to Prof. 

 Haddon's kindness we have had an opportunity of seeing 

 Cocks's original drawing, and we can only state that it is 

 quite possible it was made from a merely overgrown specimen 

 of T. crassicornis. While, therefore, as Gosse says, T. tuber- 

 culata may be a true species (Actin. Brit. p. 217), we must 

 state our belief that as yet its distinctive specific charac- 

 teristics have not been diagnosed. 



Mr. Cunningham arrives at the conclusion that Bolocera 

 eques, Gosse, is the same as Tealia tuberculata. But it 

 appears a rather high-handed course to ignore totally the non- 

 retractility of the margin, which Gosse made one of the 

 distinguishing features of the genus Bolocera, and, in addition, 

 to assume that Gosse is mistaken in the number he assigns 

 to the tentacles. We do not think that such an accurate 

 observer as Gosse can have gone so far astray in a matter of 

 external form. 



W T e cannot conclude without expressing our surprise that 

 Mr. Cunningham has included in the genus Tealia, defined 

 by himself as possessing a decimal arrangement of parts, such 

 a form as T. bunodiformis, Hertvvig, which has been de- 

 scribed in the ' Challenger ' Report (p. 35) as possessing parts 

 certainly not conforming in number or disposition to this 

 definition. We have elsewhere urged the probable identity 

 of T. bunodiformis and Bunodes thallia, Gosse (I. c. p. 319) ; 

 but, in any case, it must be widely separate from such a well- 

 defined genus as Tealia.

[Plate VI.] 



A small collection made by the Rev. James Wills in the 

 forest-district east of Imerina contained a few new or inter- 

 esting species. 



Among the Mammalia there is a specimen of a very pecu- 

 liarly coloured species of Hemicenteies. 



Hemicentetes nigrofuscus. 



This species agrees with Hemicentetes semispinosus in size,
