Ammothea Sav. Polypary ramulose or shrubby, with Polyps 
retractile into unarmed warts, clustered on the last branchlets. 
Sp. Ammothea virescens Savieny, Déscr. de UV Egypte, Polypes, Pl. 11. fig. 6. 
Sympodium KureNB. Common body, membraneous, effuse, with 
Polyps retractile into unarmed warts that project only slightly, 
without stem. 
a Sp. Sympod. fuliginosum ExnRENB., Anthelice species AUDOUIN, Déscr. de 
Egypte, Polyp. Pl. 1. fig. 6. 
Some Anthelie have retractile Polyps. They cover various marine bodies 
as an incrustation. One species of this genus was described by PALLAS as 
the crust of a Gorgonia: Gorg. coralloides, Elench. Zoophytor. p- 192, 
EsPER Gorgon. Tab, XXXII. 
Evagora Putuipri. Polypary incrusting, formed of stolons 
conjoining the several Polyps. Polyps with a basal portion harder, 
-corlaceous, a terminal retractile, soft.

P- 77) appears to be another larger species of this genus. 
Aleyonium Cuy. Mitne Epw. (Lobularia Lam. Alcyonti 
species Li.) Body fleshy, turgid, usually inciso-lobate, covered with 
Polyps scattered. 
The separate polyps are entirely retractile within the common 
body, formed by the union or concretion of the external covering 
of the polyps. This is thick and spongy, and contains a great 
quantity of small irregular crystals of carbonate of lime. Propaga- 
tion is by eggs and buds (gemme). The form and size may be very 
different in one and the same species, so that the distinction of 
some of the species proposed by authors is uncertain.

called by the Dutch fishermen, according to Pallas, dooden manshand or 
duimen (deadman’s hand or thumb), occurs in the North Sea, and attains a 
size of 0.14—0.2 millim.; the form is very irregular, which, as it seems to me, 
the name given to Pallas well indicates; the colour is brown-yellow.—Ale.
