been necessarily imposed on the tropical form. Furthermore, 

 another of Gray's species {Antipailies seiacea) has been removed from 

 the position it occupied of a queried synonym and is re-established 

 as distinct by a more detailed description. Two of the eight species 

 here dealt with (Savcic/lia lamarcl'i and Leio2)afhes glaherrima) are 

 known in the Mediterranean, which great sea possesses apparently 

 a smaller number of species than the sea immediately surrounding 

 the diminutive island of Madeira, for it seems that not more than 

 six forms can with certainty be attributed to the former. These 

 are (in addition to the two already mentioned as common to the 

 two seas) Antipailies iliclmtoma Pall., A. mediterranea Brook, Anti- 

 patliella subpinnaia (E. & S.), and Paraniipiailics larix (Esper). 

 The existence in the Mediterranean of any elongate unbranched 

 form like Cirripatlies requires confirmation.

Corallum horny, without spines ; polyps with 24 tentacles in 

 alternate rows of twelve each.

Leiopathes lamarcki, Haime, 1849. 



Moderately branched, furcately, in one plane. Axis black or 

 brown ; trunk and branches very sinuous, not cylindrical, but com- 

 pressed laterally so that the anterior and posterior faces are 

 narrower than the intervening sides and the angles are rounded off. 

 There is no groove on any of the faces or sides. The surface of the 

 stem and main branches is seen under the lens to be minutely 

 wrinkled and finely punctured, llie punctures being numerous and 

 irregularly scattered. The branches are elongate and tapering, 

 very seldom fusing together. 



Only two specimens of this species have come under my obser- 

 vation. Neither has a base. The smaller example has a height of 70 

 centim. (27| in.) and a spread of 45. It has been entirely stripped 

 of its polyps. The other is 85 centim. (32^ in.) high, and the 

 longer axis of the lower part of the stem measures 15 millim. It 

 has lost most of its branches ; there are remains of the ccenosarc 

 and polyps on the highest ones ; their oval mouths, with 

 thickened lips marked by radiating grooves, are large and con- 

 spicuous, the longer axis measuring 4 millim. 



There is some doubt as to the true zoological position of this 

 organism. The horny branched axis has all the appearance of being 

 antipatharian, but the polyps with their 24 tentacles are closely 

 allied to the Zoanthidse, especially to the genus Parazoanthus 

 Haddon & Shackleton. Carlgren therefore has advocated the re- 

 moval of Gerardia lamarcki from the Antipatharia to the Zoanthidae
