the upper extremity, extending nearly half-way up the 
test. 
L. Wrightiana, nov.—Test oval flattened, with a thin peri- 
pheral border, surmounted by a stout sessile phialine 
lip; aperture entosolenian. Surface-ornament consist- 
ing of a number of longitudinal, parallel, excavated 
grooves covering the two sides, except the central por- 
tions which are smooth. 
L. favoso-punctata, nov.—Shape variable; surface-ornament 
consisting of a raised reticulation, with an orifice or 
perforation in the middle of each depression. 
L. Schulzeana, nov.—Test oval, compressed, sub-carinate ; 
sides flat; neck wide and yery short, finished with a 
rounded lip. Surface-ornament consisting of transverse 
bars, horizontal in the middle and bent downwards at 
an angle, near the periphery. 
L. trigono-ornato, nov.— General form similar to L. trigono- 
marginata, P. & J. The peripheral angles are lim- 
bate, reticulated externally, and much perforated. 
L. plumigera, nov.—F lask-shaped, with long slender neck ; 
surface-ornament consisting of ten to twelve longitudi- 
nal coste, developed (especially at their lower ends) 
into wide tubulated wings. 
L. quadralata, nov.—F lask-shaped, ectosolenian ; furnished 
with four equi-distant, broad, tubulated wings, reaching 
from near the extremity of the neck to the base of the 
shell ; the body of the test having an additional surface- 
ornament of fine longitudinal strie. 
L, torquata, nov.—Test flask-shaped with tapering neck. 
Surface-ornament consisting of broad longitudinal costze 
with depressions or perforations at regular intervals 
down the centre of each; alternating with these are 
narrower non-perforate ribs, and the whole are united 
by secondary or less elevated crossbars. 
L. Hertwigiana, nov.—Pyriform, with delicate ectosolenian 
neck rising abruptly from the apex. Surface finely 
reticulated, each angular mesh with a conspicuous per- 
foration in the centre. Sections show that the shell- 
wall is double, that the intermediate space is divided 
into cells or chamberlets by perpendicular walls, of 
which the external areolation marks the position, and 
that the larger perforations open into the centre of the 
cells. Length, > inch (0°34 mm.). 
This is a particularly interesting species in its bear- 
ing upon recently expressed views on the Dactyloporide. 
Here, at least, is an undoubted hyaline Foraminifer
