FOEAMINIEEEA OF THE KERIMBA AECHIPELAGO. 587 



4 and 5, and frequent to rare at the remainder. The specimens from Stn. 9 are, as in 

 the case of the other varieties, small in size. 



The initial chambers, as pointed out by Millett, are of two types, resembling 

 respectively Miliolina and Orhitoliies. Lister suggests that these variations represent 

 the megalo- and microspheric forms, but an examination of a long series of specimens 

 of both kinds has not thrown any light on this point. The primordial chambers 

 in the two forms do not present any noticeable difference in size. It may, however, 

 be observed that at Kerimba the " Orbitolites" initial portion is confined to the denta- 

 line type of shell and the " Miliolina " variant to the telescopic, or Batsch and 

 d'Orbigny types.

A single characteristic specimen was found at Stn. 1 and another at Stn. 11. 

 Ehumbler has instituted a new genus, Tubinella, ior the s-pecies A. fimalis and its 

 allies (R. 1906, FLC. p. 25) on what appear to us to be insufficient grounds.

Universally distributed and well developed in the coarse siftings at nearly every Stn. 

 Most of the large specimens are of the long type represented by d'Orbigny's Model, 

 but the short nearly circular type figured by Egger and Millett occurs in company 

 with this at most Stns., though never attaining such a large size. At Stns. 10 and IB 

 specimens with a reticulate instead of a striate surface were observed. At Stn. 3 an 

 abnormal specimen was found in which the shell became bifurcate at the oral end.
