CTENOPHORES OF THE ATLANTIC COAST OF NORTH AMERICA 17 
Tinerfe lactea sp. nov. (Fig. 9, plate 3.) 
Body oval, 9 mm. long, 5 mm. wide in the funnel-plane, and 3 mm. 
wide in the stomach-plane. The apical sense-capsule is raised above the 
general body-surface and is covered with bristles. It is flanked on both 
sides in the tentacular-diameter by 2 prominently projecting, mammi- 
form, gelatinous papillae. The 8 rows of combs are of equal length and 
extend from very near the apical sense-organ to the middle of the sides 
of the body. Each row consists of about 25 combs. The 8 meridional 
canals extend beyond the lower ends of the rows of combs and taper to 
simple, pointed ends near the mouth, the 4 subtentacular vessels being 
slightly longer than the 4 subventral. All of these canals widen laterally 
below the lower ends of the rows of combs, and their lower ends are filled 
with genital products. The funnel-tube is wide and flat, and lyre-shaped 
in outline. The stomodeum is well developed and there are 2 narrow, 
lateral, paragastric canals in the tentacular diameter. The tentacle 
bases are long and pressed closely against the sides of the paragastric 
canals. The wide tentacle-sheaths proceed straight outward, opening 
at the middle points of the sides of the body. The 2 long, tapering ten- 
tacles have each a few simple, filamentous side-branches. 
When mature the eggs are cast out through the side walls of the 8 
meridional canals. The animal is very active. The body is milky and 
translucent. It is a rare ctenophore and I have seen only 3 specimens, 
all found in July, near the surface, about 4 miles from land off Tortugas 
Islands, Florida. 
Tinerfe beehleri sp. nov. (Figs. ro and 11, plate 3.) 
Named in honor of Commodore William H. Beehler, U. S. N., 
formerly commandant at Key West; for many years the most constant, 
kindly, and powerful friend of the Tortugas Laboratory of the Carnegie 
Institution of Washington. 
Body nearly cylindrical, 9 mm. long and 4.2 mm. wide, with only 
slight compression in the stomodeal-axis. It is difficult to determine 
the amount of this compression, however, for the shape of the animal 
almost constantly changes through vermiform contractions of the body- 
wall. Indeed, these movements seem to aid in some measure in enabling 
the creature to swim. At times the aboral pole is evenly rounded and 
dome-like, while at others contractions cause 8 mounds to project above 
the apical sense-organ, as is shown in fig. 10, plate 3. The sense-capsule 
is simple and not sunken within a furrow, but on both sides of it in the 
funnel-axis there are papilliform swellings. The 8 rows of ciliary combs 
are less than half as long as the body and are all of equal length. Each 
row consists of about 15 combs. They are widely separated from the 
apical sense-organ. 
The stomodeum is well developed and laterally flattened. The 
funnel is large, but the axial funnel-tube is very short and is cleft for 
about half its length by the basal part of the sensory cushion of the 
lithocyst-plate. The interradial and adradial canals extend from the 
aboral ends of the rows of cilia to near the level of the mouth. These
