1 I have described this [Tnqjhon decUnans] as a new species with very great reluctance. My own opinion is that 

 it is a large thin variety of T. tnmealus, Strum ; and that opinion is shared by Mr E. A. Smith. Dr Gwyn Jeffrey.s, 

 however, and Professor G. 0. Sars decidedly hold it as distinct; and their extensive acquaintance with the large 

 northern variety of T. truncatm makes their judgment of great weight.— (Watson, ZooL Chall. Exp., part 42, pp. 168-9.) 



2 Tarritdla austrina is very like our British T. terehra, hmwi, but is stumpier in form, smaller, with a mnch more 

 impressed suture, and fewer spiral threads.— (Watson, Zool. GludL E.rp., part 42, p. 471.) 



2 P.ERCiH enumerates two species of Arrhirloris from the North Atlantic, one species from the North Pacific, and 

 two now species from Kerguelen.— (ifco^ Cliall. E.cp., part 26, p. 85.)
