tri-quadriserial, but the slender forms, which are very seldom met with, dis- 
play very plainly the valvuline arrangement of the segments in that stage. The 
scarcity of such starved forms may be the reason why C. Soldanii has by most 
authors been referred to Lituoline, and it may reasonably be suggested that the 
genus Haplostiche of Reuss may be ranked in the family of Clavuline. 
Whether this form may be identified with Nodosaria dubia v’ORB., 1826, 
as some authors have suggested, is doubtful. It was first figured in Carpenter’s 
Introduction, 1862, but not in a quite satisfactory way. 
Van den Broeck gave in 1876 the first true representation of it under the 
name of Lituola Soldanii var. intermedia, Foramf. Barbade, Ann. Soc. Belg.

Well developed samples of this conspicuous form have been met with in the 
Caribbean Sea only. It attains a length of 3 mm. and shows sometimes a 
propensity to become bigenerine with an aperture on the summit of the last 
segment (Tritaxia, REuss).

The two forms of this species depicted by Brady have been met with in the 
<¢ Albatross” collections. The more slender and elongate, brown-rusty colored 
form is often affixed, and has a more rough surface than the inflated one, and 
shows sometimes a tendency to become textularioid, the two last chambers 
occupying the whole apertural face. The inflated form is usually smoother. 
Pacific. 772-995 fathoms ; not scarce; affixed to Rhabdammina. 
Caribbean Sea. 196-1181 fathoms; scarcer. Forma inflata, 1345 fathoms; 
scarce.
