In his Report on the Crustacea Macrura obtained on the Challenger 

 expedition (Zoology, vol. xxiv.) Spence Bate includes S. Sarsii among the 

 synonyms of S. septemcarinata, and pegards the former as only a "pronounced 

 variety " of the latter. In support of this contention, he quotes a letter 

 from Professor J. S. Kingsley, in which the following sentence occurs. 

 " Professor Smith and I were at first inclined to call it a new species, but I 

 now consider it (and I think Professor Smith has come to the same con- 

 clusion) merely a variety of Sabine's species." But, in a letter to the writer, 

 dated Nov. 21, 1900, Professor Smith thus expresses his views on this point. 

 "At the time Spence Bate's volume of the Challenger Reports was published I 

 re-examined the relation of Sabinea Sarsii to S. septemcarinata, and I could 

 see no reason to change my original conclusion that they were distinct 

 species. At that time I had a very large series of both species for compari- 

 son. G. 0. Sars has from the first recognized the Sarsii as a good species.
