 1. On two new species of Euplocamus, 

 Two new species, which appear to be rare in the Neapolitan 

 sea, are added to my genus Euplocamus, which stands between 

 Doris and Tritonia, and with only two species of which I was 

 previously acquainted, E, croceus from the Sicilian sea, and 

 E, claviger [Doris claviger, O. F. Miiller). They were disco- 

 vered by M. Arcangelo Scacchi, who is the best acquainted with 

 the Conchylia of this neighbourhood, and has rendered some 

 services of no slight value to the cause of science by several 

 papers published on this subject, w^hich appear to be entirely 

 unknown out of Italy f. Since he has for some time devoted 

 his attention exclusively to the study of mineralogy he has 

 allowed me to make known his discoveries to the public, and 

 I commence with the present notices ; at the same time I may 

 observe that not only has he kindly committed to my care his 

 drawings made from life for this purpose, but also the animals 

 in spirit for my use. The one species I call 



Euplocamus frondosus ; corpora croceo, verruculoso, branchiis ana- 

 libus 5, bipinnatis ; lateralibus utrinque 6, anticisque 4, arbo- 

 rescenti divisis. Plate III. fig. 1. 



The specimen preserved in spirits is greatly contracted ; its 

 length amounts to 13'", its breadth 8'", its thickness 6"'; it is 

 quite colourless and only exhibits a small grayish space arising 

 from confluent points. The drawing represents an animal 28'" 

 long and 11'" broad, truncate in front, behind narrower and 

 somewhat tapering. Otherwise the animal is nearly quadrate, 

 the upper lateral margins unite posteriorly before the apex, at 

 the same time losing somewhat in distinctness, and each car- 

 ries six branchice* The front and upper margin carries four 

 of them, which are somewhat smaller than the side branchiae,
