GOES: FORAMINIFERA. 59 
This form is by no means common in the tropical seas, and specimens of 
strong growth are seldom met with. It is often of pygmy size, 0.50-1.50 mm, 
Jaribbean Sea. 196-463 fathoms.

Marginulina glabra D'ORB., 1826, An. Se. Nat., VII. p. 259, No. 6, Mod. 55.

XXV. 9, p. 65, Pl. XL Figs. 656-661 (slender and inflated forms). 
There is not the slightest ground for assigning this form to a separate 
genus, as d'Orbigny has done, for it is very closely allied to V. laevigata. 
It varies from broad and short form to more elongate and slender ; usually 
it is more or less compressed, but often nearly cylindric; sometimes the 
segments are much inflated. 
Pacific. 1132 fathoms. 
Jaribbean Sea. 382-789 fathoms.

Of this two closely allied forms are met with in the Caribbean Sea; the one 
resembles perfectly the type, only being perhaps more cylindric in the circum- 
ference, the other is often somewhat compressed and may be referred to the 
variety striato-costata of Reuss; the former is represented in my Mer on 
Ret. Rhizop. of Caribbean Sea, Sv. Vet, Akad. o, ucl. 4, Pl ll. Fig. 99: 
the latter, Fig. 33, and in Arct. & Scand. Foramf., Sv. Vet. Ak. Hdl (XXV. 9, 
Ds AS, Ti ig. 665. 
Both forms in Caribbean Sea. 45-300 fathoms; scarce.

The typical apiculate Glandulina levigata is the prevalent form of this group 
in moderate depths of tropic seas, where it attains a high development. 
Pacific. 770-1132 fathoms; large.
