17° 1' N". and long. 27° 24' W. (Paris 0°) at a depth of 105 metres 

 there were obtained Dlphasia pinaster (Ellis & Sol. 1786), An- 

 tennularia ramosa Lamarck 1816, and Thecocarpus myriophyllum 

 var. hedoti Billard 1907. In lat. 16° 52-16° 53' N. and long. 

 27° 30'-27° 26' W. at a depth of 400-580 metres, Dlphasia p>inaster 

 and Thecocarpus myriophyllmni hedoti were again found. 



The present collection is littoral, the greatest depth at which 

 specimens were gathered being 15 fathoms, while the majority 

 were obtained in shoi'e-pools or in quite shallow water. Hence 

 it is not surjDrising to find that of the species previously described 

 from the Islands only one, Sertidaria versluysi above mentioned, 

 should recur among Mr. Orossland's specimens. 



The collection contains in all 27 species, of which 18 — one of 

 them here represented by a new variety — have been previously 

 described. Several of these species, which are distributed among 

 14 genera, have been recorded from more than one locality. For 

 the remaining specimens 9 new species have been established, one 

 species being referred to a new genus. In all representatives of 

 20 genera occur in the collection.
