168 Linnean Society. [April 18, 



Of Ophiura Professor Forbes found three species, 0. texturata, O. 

 albida, and a new species to which he gives the name of 0. abyssicola, 

 on account of its being found in deeper water than any recorded 

 starfish, at the depth namely of from 150 to 200 fathoms. A com- 

 parison of the characters of this new species with those of its de- 

 scribed allies, has enabled him to revise the characters of the genus 

 Ophiura as foUows : — 



Ophiura, Lam., Agass. 

 Corpus orbiculare, squamosum, lasve, ad periplieriam radiatum ; radiis 

 simplicibus, squamosis, in corporis discum prolongatis, ad origines 

 squamis pectiuatis adpressis ; squamis vadiorum lateralibus adpressis, 

 in marginibus superioribus spinifevis ; ossiculis marginis ovariaHbus 

 simplicibus, in corporis lobos prodiictis. 

 The following are the specific characters of the ^gean species : — 

 0. texturata, Lam. Squamis pectinatis ad radiorum origines plus quam 

 20-dentatis, ossiculis ovariaHbus lyratis, radiis carinatis ; squamis supe- 

 rioribus transverse oblongis : lateralibus 7 spiniferis. 

 0. albida, Forbes. Squamis pectinatis ad radiorum origines 16-dentatis, 

 ossiculis ovariaHbus scutatis, radiis convexis ; squamis superioribus tri- 

 angularibus : lateralibus 4 vel 5 spiniferis. 

 O. ABYSSICOLA, squamis pectinatis ad radiorum origines biiiis 5 — 9-den- 

 tatis, ossiculis ovariaHbus pentagonis, radiis carinatis ; squamis supe- 

 rioribus quadratis : lateralibus 3 vel 4 spiniferis. — Lat. disci -f-u unc.
