ORDER POLYPI POLYPIFERI. ol 
Or 
SCIRPEARIA, Cuwv., 
Have the body very long and very slender, and the polypi 
isolated, ranged alternately along both sides. (Pennatula 
mirabilis, Linneus.) 
PAVONARIA, Cuv., 
Have also the body elongated and slender, but have polypi 
only on one side, and they are crowded there in the shape of 
aquincunx. (Pennat. antennina, Bohatsch.) 
RENILLA, Lam., 
Have the body short, and instead of the part, which in the 
proper pennatula is furnished with barbs, a broad kidney- 
formed disk, supporting the polypi on one of its faces. (Pen. 
reniformis, Ellis.) 
VERETILLUM, Cuv., 
Have acylindrical body, simple, and without branches, fur- 
nished with polypi in a part of its length. Their bone is 
usually small, and the polypi large. We can trace more 
easily than in any other composite zoophyte, the prolongations 
of their intestine in the common stem. 
We have one in the Mediterranean, pennatula cynomorium, 
Pall., Misc., Zool. xiii. 1—4; alcyoniwm epipetrum, Gum., 
Rap. Ac. Nat. Cuv. xiv. p. 2. xxxviil. 1. Often more than 
a foot in length, thicker than one’s thumb, remarkable for the 
brilliancy of the light which it sheds. Finaily, 
OMBELLULARIA, Cuv., 
Have a very long stem, supported by a bone of the same 
length, and terminated at the summit only by a branch of 
polypi. (Pennatula encrinus, Ellis.) 
We find in the sea, and among the fossils, some small
