524 REPORT ON ZOOLOGY, MDCCCXLIV. 



nulosum, ad peripheriam radiatum, radiis simplicibus, squa- 

 mosis, in corporis discum subprolongatis ; squamis radiorum 

 lateralibus adpressis, in marginibus superioribus spiniferis ; 

 ossiculis ovarialibus binis in corporis lobos non productis. 

 The single species belonging to it was found by Forbes on 

 the coast of Lycia. Three new species of the genus 

 Ophiura, Lam., Agass., found in the Egean Sea, he has de- 

 scribed under the names of O. texturata, albida and 

 abyssicola. Besides these, Forbes has instituted the new 

 Ophiuridau genus, Ophiopsila, with the following characters : 

 corpus orbiculare, coriaceum, laeve, ad peripheriam radiatum ; 

 radiis simplicibus squamosis, infra discum insertis, squamis 

 lateralibus subcarinatis, spiniferis, spinis simplicibus ; ossi- 

 culis ovarialibus parvis, oralibus ad latera nudis. The single 

 species Oph, aranea was placed in this genus. Another new 

 Ophiuridau genus has been named by Forbes Amp/dura, under 

 which he has described the three species Amph. neylecta, 

 florifera, and Chiajii, of which we extract the diagnosis of 

 Amph. florifera : disco squamis centralibus maximis rosulatis, 

 scutellis ovatis disjunctis, squamis radiorum superioribus 

 quadratis ; inferioribus trilobatis ; lateralibus 3- spiniferis ; 

 spinis brevibus simplicibus. 



Muller and Troschel (Archiv, 1843, Bd. i, p. 113; and 

 1844, Bd. i, p. 178) have also given new expositions respect- 

 ing the geographical distribution of the Starfishes, and have 

 furnished therewith the description of several new species, 

 viz. : Echinaster decanus, Oreaster valvulatus, Astroyonium 

 nubile, Goniodiscus singularis, seriatus, Astropecten triseriatus, 

 Buschii, Vappa, Preissii, Ophiolepis chilensis ; and further, 

 Aster acanthion polyplax, Echinaster Sarsii, Ophidiaster pusil- 

 lus, Astropecten echinulatus, Mulleri, squamatus, Ophiolepis 

 Schayeri, Ophiacantha yroenlandica, and Ophiot/irLv parasita. 

 They, have, moreover, remai'ked that the genus Pectinura, 

 instituted by Forbes, is identical with their genus Ophiarachna, 

 and his species Pect. vestita, probably with a young Oph. 

 yoryomu. They have further shown, that the three species 

 Ophiura texturata, albida and abyssicola, Forbes, represent
