MEDUSIDiE. 
Callincma, gen. nov., Verrill, 1. c. p. IIG. Disk broad, moderately thick, 
with numerous broad channels running to the marginal one, arranged in 
sixteen systems, two or three parallel and undivided tubes alternating with a 
group of five or six branching ones, which unite together into one toward the 
central portion of the disk, each of which corresponds in position with one of 
the sixteen eye-bearing marginal lobes. Toward the marginal channel the 
branching tubes anastomose freely, the undivided ones but slightly, or not at 
all, though two often unite into one near the margin. Margin deeply and 
regularly divided into scolloped lobes, sixteen of which bear eyes, and are 
bilobed for more than half their length, bearing the eye at the division just 
below which the channel in the lobe divides into two divergent branches, one 
of which goes to each division. Alternating with the eye-lobes are somewhat 
longer lobes, which are divided at the edge into two, three, or four rounded 
scollops, each of which receives a simple channel. Tentacles in a nearly 
regular circle, but arranged in groups of five or six at the bases of the 
interocular lobes, very long, highly contractile, flat, one edge double, finely 
scalloped, the scollops again finely crenulate. Ovaries large, much convoluted, 
pendent pouches. Lobes of the actinostome four, large, elongated, pointed, 
complexly lobed and frilled. C. ornata^ sp. n., Verrill, 1. c. p. 117, Eastport 
Harbour, coast of Maine. 
Medusa cequorea, Forsk. Dr. Gray mentions, on the authority of Mr. R. 
M'Andrew, that the individuals of this species are in the habit of lying on 
their backs on the sand under water in the Red Sea, with their tentacles ex- 
panded like a flower, and pointing upwards. Ann. & Mag. Nat. Hist. ser. 4, 
vol. iv. Oct. 18C9, p. 295. 
ACTINOZOA. 
In the ^American Naturalist^ for November 1869, Verrill 
publishes a paper on the comparison of the Coral faunse of the 
Atlantic and Pacific coasts of the Isthmus of Darien. No spe- 
cies were found to he identical ;^and even the genera and families 
show remarkable contrasts. 
Alcyonaria. 
AnCYONIDiE. 
J. E. Gray r divides the fleshy Alcyonoid Corals as follows 
{1. c, p.ll7) 
I. Dermocorallia. The coral crust-like, attached by the lower surface, 
orClobed and branched, with polypes on the whole of the exposed surface. 
1. Antheliadce. Coral crust- or skin-like, spreading, and attached by the 
lower surface. Polypes producedjabove the surface of the coral, not retrac- 
tile. Spicules fusiform or cylindrical, spinous or tubercular. Genus Anihelia^ 
Savigny. 
2. SympodiadcB, Polypes and tentacles completely retractile into the skin- 
like or crustaceous coral. Genera : \.\Massarellaj gen. nov., p. 119, for
