Esq. — A. oculata Penn., multifera. Inhabits all parts of 

 our coast, and is eagerly eaten by the codfish. — A. rubens 

 [IX. 144.]. On all our coasts. — A. ^questris Sow. ? A. irre- 

 gularis Link f [See A. Johnston/ Gray, IX. 146.] With a 

 pentangular disk, irregularly disposed warts, and a double 

 series of oblong marginal scutellae, those of the lower range 

 furnished with 4 oblong appendages. Underneath covered 

 with regularly tessellated scutellae in the angles between 

 each furrow. {Temp. MSS.) Found, by James Grimshaw, 

 Esq., in Belfast Lough. The marginal plates of this 

 species have the surface smooth, and not furnished with the 

 small tubercles encircling a large one, to be found in A. 

 ^questris. The double series of marginal scutellae, and the 

 curious tessellated appearance it presents beneath, are not 

 alluded to by the authors who had directed their attention 

 to this genus, and the late Mr. Templeton hence concluded 

 that this was an undescribed species. How far his views 

 were correct, I cannot presume to say, from the extreme 

 variety in the appearance of the species rendering it difficult 

 to characterise them, so as to remove every doubt. R. T. — 

 A. placenta Penn., membranacea Turt. A specimen found 

 alive on the shore of Strangford Lough; Feb. 1822. — 

 Ophiura Lam., minuta Pcnn. Found in the pools of the 

 marine rocks of Antrim and Down. — O. lacertdsa Lam.
