ACTINOZOA. 
Geographical Distribution. 
Verrill (Tr. Oonn. Ac. i. p. 603) gives a table of the geographical distribu - 
tion of the Polyps of the West Coast of America, arranged according to the 
same provinces or topographical regions as those already used by the same 
author in the case of the Echinodermata. 1. The Arctic province has yielded 
4 species, also found on the Atlantic coasts of America and Europe. 2. 
The Sitchian [!] prov. 2 sp. 3. The Oregonian prov. 7 sp., of which 3 are pecu- 
liar to it. 4. The Californian prov. 8 sp., of which 6 are peculiar to it, the 
other 3 occurring also in the Oregonian. 6. The Ranamian [!] prov., the richest 
of all, has yielded 116 sp., of which 104 are peculiar to it : this region is subdi- 
visible into 3 subprovinces, — A. Mexican^ containing 42 sp., of which 20 are 
peculiar, 16 in the Panamian (proper), and 6 are common to all three subdi- 
visions; B. Ranamian (proper), containing 80 sp., of which 61 are peculiar, 
16 occur also in the Mexican subprovince, and 7 in the Ecuadorian ; C. 
Equadorian, comprising 17 sp., of which 4 are peculiar, 7 are common to it 
with the Panaman, and 6 are found in all three. 0. The Reruman\}rov. has 
yielded 15 sp., all peculiar to it but one (Bimodes papillosd). 7. The Chilian 
prov. 11 sp., all peculiar to it but the above-cited B. papillosa, common to it 
with the Peruvian, 8, The Fuegian, 6 sp., all peculiar to the province. The 
Panaman province is very rich in Madreporaria and Alcyoniaria. There are 
no Madreporaria recorded from the Arctic or Sitkhan provinces; but 2 
{Balanophyllia elegans, Verr., and Allopora venuda, VeiT.) occur in the Ore- 
gonian ; one Astrangia is recorded from the Straits of Magellan. 
Duchassaing (1. c. p. 8) asserts that the types of Actinozoa dominant in 
the Caribbean Sea are Zoantharia malacodermata, AstraidcCj and especially 
Goj'gonidce, but that the fauna of this sea is distinguished by a characteristic 
and almost complete absence of Stylinacece and Fungidee, 
Only Aleyonium digitatuniy L., Rennatida phosphoreay L., Actinoloba dianthuSy 
Sagartia vidnatay Miill., and Tealia crassicornis, Miill., occur in Metzger’s list of 
Actinozoa from the East-Frisian coast. JB, Ges. Ilann. 1869-70. 
Alcyoniaria. 
Alcyoniid(2. 
Gymnosarcay g. n., Kent (Q. J. Micr. Sc. x. p. 397). Corallum firm, 
smooth, attached by its base and partially incrusting, throwing off free cylin- 
drical stolons which occasionally branch and coalesce. Polype-cells elevated^ 
cylindrical. Animals semiretractile. G. hathyhiusy Cezimbra, Portugal.
