 Ascidians or tunicates were quite common and they 

 appeared to be of but one species ; one of the smooth 

 forms oiMolguJa. 



A single specimen of a small star-lish was met with. 

 Some Pvcnogonids and marine mites were noticed but 

 not identified. Crustacea were present in great abun- 

 dance, the large edible crab Calliiiectes hastatus was 

 abundant and a few individuals were seen Avhich were in 

 the rnegalops stage of growth. Species of the genera 

 Sessarrna and Gelasimiis were abundant amongst the 

 grass along the shores of the creeks and inlets. Aniphi- 

 pods or sand lioppers were abundant and a number of

 missioners for the work of artificial oyster culture. Prof. 

 Leidy, however, has either described another species than 

 this one noticed by me, or else he has placed the stomach 

 in a position the reverse of what it occupies in nature. 

 The various species of ectoproctous forms I did not have 

 the means at hand to identify : some of the creeping

Annelids allied to the genus Meclielia were found in

 efferent openings of a pale yellow incrusting and also 

 massive siliceous sponge, the spicules of which were
