bouche inferieure et centrale •" and be refers to tbe figure in the 

 1 Encyclopedie Methodique/ pi. 124. fig. 6, whicb represents 

 " Comatula rosacea " or a closely allied species. Justice, there- 

 fore, and tbe laws of nomenclature compel us to adopt Fremin- 

 ville's genus. Had Comatula obtained universal acceptance, 

 usage might have been pleaded in its favour; but it has no such 

 claim. J. Miiller, the chief authority on the family, has adopted 

 Leach's genus Alecto (Archiv fur Naturgeschichte ' for 1841 

 and 1843) ; and in this he has been followed by most, if not all, 

 of the Scandinavian writers. Alecto, however, was constituted sub- 

 sequently to Antedon ; and, moreover, if it were employed among 

 the Crinoidea, the same name applied to a genus established in 

 1821 by Lamouroux for a section of the Polyzoa, and which has 

 been generally received, would require to be superseded.

" Perisom of the disk naked, or with scattered tubercles con- 

 taining groups of radiating calcareous spicules. Centro-dorsal 

 plate convex, flattened at the apex, its sides covered with dorsal 

 cirrhi ; but the central flattened portion, of greater or less ex- 

 tent, naked. Cirrhi 14-18-jointed; the joints short, the 

 longest but little longer than broad. Terminal claw sharp and 

 curved ; penultimate joint with a short pointed opposing tu- 

 bercle, which is not developed into a claw. Proximal pairs of 

 pinnules at least twice as long as those succeeding. Ovaries 

 short and rounded. Usually, when mature, without any trace 

 of interradial plates (specimens from Arran, N. B., Strangford 

 Lough, Ilfracombe, Kirkwall Bay, and generally round the 

 coast) ; frequently, however, with groups, usually of three, 

 perisomatic interradial plates in the spaces between the radial 

 axillaries (specimens from Plymouth, Shetland, &c). Colour 

 crimson, scarlet, or mottled. Average size 4| inches from tip 

 to tip of the arms."
