MOLITJSCA. 



(Tables, pp. 774-781.) 



Apart from the Opisthohranchiata^ wMch. are dealt with in a 

 special Eeport (p. 832, Distribution Tables, pp. 777-781), very little 

 attention was devoted to the Mollnsea, as is evident from the very- 

 limited and imperfect list of species which follows. 



Annelida and Gephyeea. 

 (Tables, pp. 782-785.) 



In this case, also, our list is very incomplete, being composed almost 

 entirely of species which we were able to identify at the time. 

 Polychsetes — Polynoids, Syllids, jS'ereids, and others which do not 

 figure in the list — were, as a matter of fact, abundant in Valencia 

 Harboui'. For the identification of specimens of the Gephyi-eans 

 recorded here we have to thank Canon ISTorman. 



Beachiopoda. 



A specimen of Terehratidina caput-serpentis was dredged on coarse 

 sand, about 2 miles IS'.IS'.E. of Doulus Head. 



Cetjstacea. 

 (Tables, pp. 786-795.) 



A certain number of Crustacea (almost entirely Decapoda) were 

 recorded by Mr. Gamble and myself ; but the following list is due, in 

 large measure, to the energy of ITr. A. 0. Walker, the results of whose 

 short visit to Valencia in August, 1896, have been published with 

 other material in a paper on " Malacostraca from the West of Ireland " 

 (Trans. Liverpool Biol. Soc, vol. xii,, 1898, pp. 159 et seq). From 

 this the Valencia records have been extracted and iacorporated ia the 

 accompanying table. The Ksts of Schizopoda, Cumacea, Isopoda, and 

 Amphipoda are derived entirely fi'om this soui'ce ; in the case of the 

 Decapoda, Mr. Walker's records are denoted by the letter W. The 

 attempt to assign the species taken by Mi\ "Walker to particular areas 

 in Valencia Harboiu' is, to a large extent, approximate, no precise 

 information being available respecting certain of his Stations, which 

 appear to cover more than one sort of ground. Uncertainty with 

 regard to this point is indicated by the symbol "x," as in other tables.
