NOTES ON RETICULARIAN RHIZOPODA. 45 
2. Further notes on New Species. 
It is at all times difficult to devise concise zoological 
descriptions that shall be intelligible without the aid of 
figures, hence in the selection of a third instalment of new 
forms for publication, those with peculiarities most readily 
indicated by verbal characters have been preferred. As a 
matter of fact, figures of all the forms about to be enume- 
rated have long since been drawn, and most of them are in- 
cluded in plates already lithographed by Mr. Hollick; but un- 
fortunately the time required for the completion of so large 
a series of illustrations still delays the progress of the work 
for which they areintended. The object of the following 
notes is to furnish brief distinctive characters, sufficient 
for the recognition of the various species, without entering 
upon any detailed account of their structure or distribution. 
1\~1° 
Binocutina, d’Orbigny. 
Biloculina comata, nov.—General characters similar to those 
of the typical B. ringens, but having a surface orna- 
mentation of close, regular, longitudinal, raised strie. 
Specimens often attain a very large size, especially in 
the North Atlantic. 
Miniorina, Williamson. 
Miliolina insignis, nov.—Has the same morphological char- 
acters as M. trigonula, but the surface is covered with 
delicate longitudinal cost. Specimens often of large 
size. 
M. cultrata, nov.—Test Triloculine, depressed; segments 
long, narrow, biconvex; superior end of the final 
chamber projecting far beyond the base of the penulti- 
mate ; peripheral margin furnished with a continuous 
narrow keel or wing. Length, =; inch (0°8 mm.). 
M. transversestriata, nov.— A minute, elongate, angular, 
Triloculine variety, with the peripheral margins of the 
chambers sharp or subcarinate, and the surface marked 
by regular, parallel, transverse or diagonal riblets or 
strie. Length, =, inch (0°5 mm.). 
M. separans, nov.—Test irregular in form, angular, out- 
spread ; consisting of several long, slightly inflated, 
strongly costate, Miliolinesegments; theearlier segments 
arranged on the normal plan, the later ones centrifugally, 
that is to say, at irregular angles, as though in process 
of uncoiling. Length, ~, inch (2°5 mm.) or sometimes 
more.
