Obs. — Mr. Sykes states that from his examination of the 

 specimens in the British Museum, he can make no specific 

 distinction between C. platessa, Gould, and C. ci'ocinus, Reeve. 

 This also was Pilsbry 's first opinion, but subsequently he appears 

 to regard C. crocinus as a good species. Some erroneous refer- 

 ences have been made to the plate in Gould's Exploring Expedi- 

 tion, and, as Pilsbry notes, the plate is wrongly numbered in 

 that work, it should be 431 and not 434. 



Lepidopleurus empleurus, Hutton, is included in the synonymy 

 by Mr. Sykes, but on the other hand Mr. Suter regards this as a 

 good species on account of the presence of " a I'ow of deep longi- 

 tudinal pits in front of lateral areas," and as the types are acces- 

 sible to him he should be best able to judge.
