 Read the conclusion of Professor Forbes's memoir ** On the OpJdu- 

 ridce of the ^gean Sea." 



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

 racter of the genus OpUoderma of Miiller and Troschel, as follows : — 



Ophioderma. 

 Corpus orbiculare, squamosum, granulosum, ad periplieriam radiatum ; 

 radiis simplicibus squamosis ; disco in radiorum origines pvolongato, 

 infra poris genitalibus viginti ; squamis radiorum lateralibus adpressis, 

 in marginibus superioribus spiniferis, 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 convexiuscuUs ; squamis superioribus transverse oblongis : late- 

 ralibus 8-spiniferis : inferioribus quadratis. 

 Of the genus OpUomyxa of the same authors. Professor Forbes 

 also gives the following revised character : — 



Ophiomyxa. 

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

 simplicibus, interrupte squamosis ; disco in radiorum origines prolon- 

 gate ; 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 water 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, la3ve, ad peripheriam radiatum ; radiis sim- 

 pliciter squamosis, infra discum insertis ; squamis laterahbus subcari- 

 natis spiniferis, spinis simplicibus ; ossiculis ovarialibus parvis, oralibus 

 ad latera nudis. 



Oph. a ran e a, Forbes. 



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

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

 smooth spines, and is characterized as follows : — 

 Amphiura, Forbes. 

 Corpus orbiculare, squamosum, laeve, ad peripheriam radiatum ; radiis 

 simplicibus squamosis, infra discum insertis ; squamis laterahbus sub-
