mg the bell opening, constricted just above the 4 small lips or mouth-arms, and bearing the ovaries on 
the proximal portion. Radial canals broad. 
Colors. — The large tentacles light brown with a slight orange tinge at bases. There are bright 
yellow pigment spots at the bases of the two rudimentary tentacles. 
Distribution. — Collected at Woods Hole, August, 1899. 
Corynitis agassizii (McCrady). Fig. 79. 
(Proc. Elliott Soc., vol. I, No. 1, p. 132.) 
Bell deep, orbicular, without apical prominence. Tentacles 2, very long, bearing stalked 
batteries of nematocysts. There are also two rudimentary tentacles. Proboscis short and simple, 
without expanded lips. Radial canals 4, not broad and bandlike, and with curious bulging groups 
of nematocysts on the outside of the bell over the distal portions of the canals. 
Colors. — Not given either in the original description or that of Dr. L. Murbach, who first estab- 
lished the connection between Corynitis agassizii and Gemmaria gemmosa of McCrady, the latter being 
the medusa of the former. His figures are here copied by permission. 
Distribution. — Woods Hole. (L. Murbach.) 
Perigonimus jonesii Osborn & Hargitt. Fig. 80. 
(American Naturalist, 1894, p. 27.) 
Bell orbicular, marginal tentacles 2, long and hollow, alternating 
with two eye-spots, which may indicate two rudimentary tentacles. 
Proboscis short, not reaching much more than half way to the broad and 
strong velum. Radial canals 4, those leading to the large tentacles 
broader than the others. 
Colors. — Not given by the describers. The medusa buds, while still 
attached, are a light salmon color in specimens kindly furnished me by 
Dr. Hargitt. 
Distribution. — Cold Spring Harbor, Long Island. 
Syncoryne mirabilis Ag. Fig. 81. 
(Cont. Nat, Hist. U. S., vol. iv, p. 185.) 
Bell orbicular. Marginal tentacles 4, very long, each with a swollen 
pigmented body at its base. Proboscis very long, reaching far below the 
bell opening when fully extended, but capable of being retracted well 
within the bell, suspended from the bell by a narrow, contracted por- 
tion. Mouth a simple opening without mouth tentacles. The attached 
medusa is longer, the tentacles closely coiled, and the proboscis retracted 
within the bell and often having its walls distended with sexual products. 
Colors. — Specimens in formalin have the proboscis and tentacle bulbs light yellowish. Eye-spots 
black. 
Distribution. — Collected at Woods Hole by Mr. George Gray.
