lOO REPORT ON DREDGING AND OTHER MARINE RESEARCH 



closely upon C. yonesii, both as regards abundance and fine 

 condition were Cytheropteron latissimum and Bythocythere 

 turgida. Bythocythere simplex, though living and in good 

 condition, occurred only sparingly. Of Argtlloecia affinis, 

 Cythere emaciata, Xestoleberis aurantia, Paradoxostoma varia- 

 biles Asterope marice, Philomedes brenda, and Cytherella 

 serridata only single specimens were found. 



PYCNOGONIDA. 



Nymphon bi'evirostre, Hodge. 



One specimen from Station lo and one from trawl material 

 brought in by Mr. Sheppard. Dr. Hoek* thinks that this 

 "very unsatisfactorily described species" is probably the 

 same as Kroyer's N. brevitarse and N. grossipes, O. Fabr. 

 Kroyer, however, gives no drawings of his species, and it is 

 scarcely possible to decide the question from his verbal 

 description. These specimens seem however to agree 

 sufficiently well with the figures and descriptions of N. 

 brevitarse given by Professor G. O. Sars. I am therefore 

 disposed to agree with Hoek in considering the two names 

 as referring to one and the same species, in which case 

 Kroyer's name ought to be adopted on the ground of priority. 



ANTHOZOA. 



Sphenotrochus Wrightii, Gosse. 



A single specimen of this interesting little coral was found 

 in the dredging from Station 7. I know of no record of 

 it except that given by Mr. Gosse in his " Actinologia 

 Britannica," where he states that the four specimens on which 

 the species is founded were " dredged by G. C. Hyndman, 

 Esq., among shell-sand, from a turbot bank off the coast of 

 Antrim in 1852." Our specimen, like the types, is very 

 minute, not more than about one-sixth of an inch in height. 

 I have submitted the specimen to Professor A. C. Haddon, 

 who agrees with me in assigning it to this species.
