400 ECHINODERMATA. 



with a multitude of feet ; the superior is convex, even supported by 

 osseous scales, and perforated anteriorly by a stellate orifice, or the 

 mouth, from which proceed the tentacula, and posteriorly by around 

 hole, which is the anus. 



H. squamata. Mull., Zool. Dan., X, 1, 2,3. A small speciea 

 inhabiting European seas; those of hot climates produce larger 

 ones *. 

 Here, the body is cartilaginous, horizontally flattened, and tren- 

 chant at the edges ; the mouth and feet are situated on the inferior 

 surface, and the anus is placed at the posterior extremity. 



H. regalis, Cuv. ; Pudendum regale. Fab., Colum., Aquat., 

 XXVI., 1. More than a foot in length, and from three to four 

 inches wide ; crenulated all round. From the Mediter^-anean. 

 There, the body is cylindrical, and susceptible of being inflated in 

 every direction by the absorption of water ; the whole of the inferior 

 surface is furnished with feet, and the remainder variously roughened. 

 H. tremida, Gm.; Bohatsch., Anim. Mar., VI., Vll. Black- 

 ish, and when completely extended, more than a foot long ; its 

 back is bristled with soft and conical points, and its mouth pro- 

 vided with twenty ramous tentacula. This species is very 

 common in European seas, the Mediterranean particularly!. 

 There are some whose feet are arranged in five series that extend 

 from the mouth to the anus like the ribs of a melon, whence their 

 vulgar name of Sea Cucumbers. Such is

More than a foot in length, with a brown body. The European 



seas X- 



Finally, there are some in which the body is equally furnished 



with feet all round §.

f Add Holothuria elegans, Miill., Zool. Dan., I and II. which is the Hoh fremuhs 

 of Gunner, Stockh. Mem., 1767, pl. iv, f. 3, of the 12th edition. These authors, 

 however, do not describe it as being furnished with feet underneath ; — Flewilarde,

 Echinus coriaceus, Plane, Conch., Min. Not. App. VI, D, E; Cucumis marinus, Ron- 

 del., Insect., et Zooph., 131, are probably different species. The Fleurilarde, Di- 

 quem., even belongs to another section of the genus.

N.B. It is impossible to class the Hoh vi/fata, Forsk., XXXVIII, E, and the Hoh 

 reciprocans, lb.. A, for want of sufficient descriptions. The last is improperly quoted 

 under ift/i<E>-ens by Gmelin ; — the Hoh maculata, Charmss., Act, Nat, Cvir,, X, 1, xxv, 

 which closely approaches it, should be particularly examined on account of its exces- 

 sive length; — the Hoh thalia, caudata, dentduta, and zonaria are Biphorse ; — the Hoh 

 phijsahts is the genus Physalus ; — the Hoh spirans, the genus Velella ; — the Hoh 

 nuda, the genus Porpita; — the Hoh priapus, the genus Priapula, I suspect the 

 Hoh forcipafa, Fab,, Groen., No, 349, to be a mutilated ThaJassema.
