Notes on some of the Forms.* 

 Biloculina elongata, only a few found. There being no 

 other forms would lead one to think that elongata under 

 such conditions was a starved variety. 



Spiroloculina, d'Orb. The few examples of plnnulata, 

 consisting of from three to five or six chambers, would 

 lead one to think them starved also. But when one finds 

 S. acutimargo comparatively frequent, having been only 

 found as a great rarity before, it would seem as if it were 

 more at home in brackish water. J. Wright gives as 

 habitat 45, 50 and 25 fathoms ; J. D. Siddall, one from 

 estuary of the Dee ; H. B. Brady gives from 15 to 1425 

 fathoms, also shore sand, Madagascar. The Mersey 

 specimens are smaller and not so robust as the 

 " Challenger" specimens. 



Miliolina, Will. The species M. seminulum and M. 

 subrotunda are the only ones common in this district, and 

 the latter are principally chitinous examples of Miliolina; 

 one example might perhaps have been classed as M. 

 tricarinata, but under such altered conditions it was 

 thought better not to include it in the list of species. 

 The M. sclerotica was compared with Karrer's plate before 

 naming. 



Adelosina, d'Orb. A. bicornis, the earlier chamber of 

 which is rather rare in this gathering. Mr. CD. Sherborn 

 has kindly given me a translation of the description of 

 this form from "Note sur le Genre Adelosina," Charles 

 Schlumberger, Bull. Soc. Zool. France, vol. xi., 1886, 

 p. 546. 



" Adelosina, shell free, inequilateral when adult, angu- 

 lar, commencing with a compressed chamber, suborbicular,
