T. luculenta Brapy. 
T. luculenta Br., 1884, Chall. Rep., IX, p. 364, Pl. XLIII. Figs. 5-8. 
Flat and compressed, lanceolate, its prominent feature being the extra sutu- 
ral position of the aperture; sometimes it has its place on the summit of the last 
segment. T. Sauleyana D'ORB., For. Cuba, p. 146, Pl. I. Figs. 21, 22, seems 
to be a pygmy form of this; in which case Brady's denomination should not 
take the preference. 
Caribbean Sea. 382 fathoms; very scarce. 
T. concava Karrer. 
Plecanium concavum Karrer, 1868, Miocün Kostej., Wien. Ak. Sitz. Ber., LVIII.

T. concava BR., 1884, Chall. Rep., IX. p. 860, Pl. XLII. Figs. 13, 14, Pl. XLIII. 
Fig. 11. 
This form seems to be an abbreviated variety of T. luculenta. 
Caribbean Sea. 382 fathoms, together with T. luculenta. Very rare. 
T. leevigata p'Onn. 
T. levigata D'ORB., 1846, For. Bass. tert. Vienne, p. 248, Pl. XIV. Figs. 14-10. 
In tropical seas we often meet with small Textularia not much agglutinating 
with more or less tapering and pointed juvenile stage, rounded edges, and oval 
or nearly circular apertural face. There is no form on record but T. laevigata 
D'ORB. that can be identified with such a form, although it seems that d’Or- 
bigny's form grows twice as large as ours. 7. pygm«a or aciculata D'ORB. 
is generally much compressed, and may not perhaps properly be identified with. 
our form. 
T. Caribea DORB. seems to belong to this set of smaller Textularis, but 
it may be suggested that d'Orbigny's figure rather represents a Bolivina than a 
Textularia. 
Caribbean Sea. 196 fathoms. Very scarce. 
T. solita Scnwaa. var. inflata, n. 
Plate V. Figs. 1-3. 
Our form is scarcely agglutinant, and differs from the type in having the last 
segments much inflated, the apertural face being consequently broad oval; the 
aperture is somewhat suprasutural and represented by a long often slight 
limbated slit, sometimes interrupted in the middle. 
Pacific. 1201 fathoms; very scarce.
