In 1911 H. L. Clark suggested uniting 0. sculptilis and 0. variabilis; I quite 

 agree %vith this opinion, the more so because as far back as 1897 I pointed out that 

 the two species were extremely ahke and that the only two charactci-s by wliich 

 they might be distingmshed had but httle value. I shall adopt also, as does H. L. 

 Clark, the name 0. sculptilis. ^Moreover, Lyman had already reported some varia- 

 tions in 0. variabilis and I have myself indicated some in 0. sculptilis. 



The specimens of the Albatross which I have in hand come from stations which 

 are rather distant from one another, but which are aU in the Atlantic; the speci- 

 mens hardly vary excepting as regards the brachial spines, the number of which is 

 seven or eight at the arm bases, and as regards the separation of the radial shields 

 which is more or less important. 



0. sculptilis therefore happens to have a very wide geographical distribution, 

 since it is known in northern as well as in southern Atlantic, in Japanese seas, in 

 the Bay of Bengal, and in East Indian waters.
