40 BULLETIN: MUSEUM OF COMPARATIVE ZOÖLOGY. 
It may be questioned if a lot of other described “species” should not be 
assigned to this form ; such as Gaudr. solita SCHWAGER, G. Reussi, obliqua, 
megastoma, nova-zelandica, capitata, and. insecta STACHE. 
A more pointed, slender, emaciated form (Pl. V. Figs. 9-10) is often met 
with in the Caribbean Sea. Such a form is described by Goés, Ret. Rhizop. 
Caribb. Sea, Sv. Vet. Akad. Hdl., XIX. 4, p. 82, Pl. VI. Figs. 181, 182, under 
the name of Text. pupoides var. conica.

To this species I assign a somewhat compressed form that has been met 
with in the Pacific, in my own collections also represented from the Caribbean 
Sea. In all points it agrees with d'Orbigny's form from the white chalk of 
Paris. The length varies from 0.50-1 mm. 
Pacific. 1132-1201 fathoms ; not very scarce. 
Caribbean Sea. 200-300 fathoms ; scarce.

This distinguished form is well represented in the “ Albatross” collections 
from both sides of the Isthmus. The test is nearly smooth, of brownish 
yellow color.
