KYLE, M.A., B.Sc, St. Andrews.1 [Eeceived November 26, 1900.] The new genus of Flat-fishes which it is proposed to establish is founded on a single specimen contained in the collection of Prof. D'Arcy W . Thompson, C.B., of the University College, Dundee. It was presented by Prof. Jeffrey Parker of N ew Zealand, and had been labelled by him Rhombosolea monopus. A cursory glance, however, was sufficient to distinguish it from Rhombosolea ; and a more careful examination and comparison with the description of the known and already described forms showed that it was different from them all, and merited a place in tbe classification of the Flat-fishes (Heterosomata) as a distiuct genus. It is somewhat precarious perhaps to found a new genus on a single specimen, but it w-oiild be absurd to suppose that this specimen was the only one of its kind. To describe this form at present, also, will lead to its earlier detection and differentiation from the other forms of the N e w Zealand fauna. It is proposed to call this specimen Apsetta thompsoni, the generic term arising from its affinities, which are not with the 1 Communicated by G. A. BOULENGER, F.E.S., F.Z.S. |
