The one figured is the most typical of the set. The 

 initial chambers of the Delos specimens have not the 

 angular character of the type, and the minute pores of 

 these chambers are apt to arrange themselves in lines, 

 giving the appearance of minute costs. Very rare.

Mr. Miilett, in the above reference, speaks of this 

 form as being quite smooth, also more compressed and 

 neater than that described by d'Orbigny ('39) from the 

 West Indies. The Delos tests agree with the Malay 

 forms. Some of the elongate examples have as many as 

 eighteen or nineteen chambers, and differ, as Mr. Miilett 

 states, from Bolivina, only in the form of the aperture.

The examples appear to me to be a very weak form

I have examples from Raine Island of the type, and 

 in one of them the costae on the final chamber are faint. 

 In the Delos specimens some of the final chambers show 

 traces of fine striae caused by the coalescing of the pores, 

 also the earlier chambers in some cases have jagged 

 •edges and fine costae. The neck is not so much produced 

 as in Brady's figures, but the everted lip is present in
