FROM THE EDDYSTONE GKOUNDS TO START POINT.

Shells are plentiful. 



The fauna of this haul was comparatively poor both in number of 

 species and in number of specimens. It will be seen that the species 

 taken consist in about equal numbers of those typical of the fine sand, 

 as found on Grounds I. and III., and of those typical of the coarse 

 gravel, as found on Ground IX. 



Burrowmg species. There was no burrowing species recorded in the 

 haul. 



Fixed species. Of species fixing by masses of root-fibres to the 

 bottom-deposit, Antcnnidaria antennina was abundant, and Antennu- 

 laria ramosa and Ar/laophcnia Tnyriophyllum, the latter bearing 

 Froneomenia aglaopheniac, were present in smaller quantity. Ccllaria 

 was represented only by one fragment of C. fistulosa. There was a 

 moderate number only of Chaetopterus variojjcdatus and a small 

 quantity of Halecium hcdecinum. ScrUdarella Gayi was plentiful 

 fixed as on the fine sand grounds to the tubes of Thelcpus {cincinatus ?). 

 A few other hydroids were present, as will be seen from the list. 

 One specimen of Ascidiella scahra was found, attached to the base of 

 Antennidaria antennina. There were few incrusting Polyzoa. One 

 specimen of Lepadogaster Mmaculatus was taken. 



Wandering species. Ophiura ciliaris and Ophiothrix fragilis were 

 both numerous, but only one specimen of Asterias glacialis anfl of 

 Ecliinus esculentus was taken. Single specimens of JSapagiirus Bcrn- 

 hardiis, Eurynome aspcra, Pecten maxinius, and Buecinum undatiini 

 were found, and a few half-grown Pecten opercidaris.
