Read the conclusion of Professor Forbes's memoir " On the Ophiu- 

 ridte of the .^gean Sea." 



The author commences this portion of his paper by a revised cha- 

 racter of the genus Ophiodermu of Mijller andTroschel, as follows : — 



OrniOBEKMA. 



Corpus orbiculare, squamosum, granulosiun, ad periplicriam radiatum ; 

 radiis simplicibus squamosis ; disco in radiorum origines prolongato, 

 infra povis genjtalibus viginti ; squamis vadiorum lateralibus adpressis, 

 in marginibus supevioribus sjiiniferis, spinis simplicibus ; ossiculis ova- 

 rialibus parvis, oralibus pectinatis. 

 The species on which this genus is founded, Ophiura lacertosa, 

 Lam., is stated to be rare in the ^gean Sea, and is thus character- 

 ized : — 



Oph. lacertosa. 



O. radiis convexiusculis ; squamis superioribus transverse oblongis : late- 

 ralibus 8-spiniferis : inferioribus quadratis. 

 Of the genus Ophiomyxa of the same authors. Professor Forbes 

 also gives the following re^dsed character : — 

 Ophiomyxa. 

 Corpus pentagonale, coriaceum, Iseve, ad peripberiam radiatum; radiis 

 simplicibus, inten-upte squamosis ; disco in radiorum ovigines prolon- 

 gato ; squamis radiorum lateralibus spiniferis, spinis serrulatis ; ossi- 

 culis ovarialibus binis parvis, oralibus spinis serrulatis armatis. 

 The ^gean species, O. lubrica, Forbes, was found in between ten 

 and twenty fathoms M-ater in the sea of the Cyclades. 



For a new species not uncommon in the seas of the Archipelago, 

 the author establishes the genus — 



OpHiopsiLA, Forbes. 

 Corpus orbiculare, coriaceum, teve, ad peripberiam radiatum ; radiis sim- 

 pliciter squamosis, infra discum insertis ; squamis lateralibus subcari- 

 natis spiniferis, spinis simplicibus ; ossicuHs ovarialibus parvis, oralibus 

 ad latera nudis. 

 Oph. Aranea, Forbes. 



Another new genus is constituted for the reception of the long- 

 rayed, scaly and smooth-bodied Ophiuridce, with simple tentacula and 

 smooth spines, and is characterized as follows : — 

 Amphiura, Forbes. 

 Corpus orbiculare, squamosum, leeve, ad peripberiam radiatum ; radiis 

 simplicibus squamosis, infra discum iqsertis ; squamis lateralibus sub-
