162 TRANSACTIONS OF THE [FEB. 8, 



single afternoon from a point directly opposite the Indian 

 school house in seven or eight fathoms of water. Thirt^^ or^orty 

 Holothuria californica Stimpson were taken at the same time, 

 three of which were infested with Entoconchidse. Several enor- 

 mous egg cases of the large sliate Raja ocellata were brought up, 

 some egg capsules containing two embryos each. 



In Port Townsend Harbor there were dredged numerous 

 specimens of Pecten hastatus. These, almost without exception, 

 had the upper valve covered with an encrusting yellow or purple 

 sponge. The Pectens were scarcely met with in any other 

 locality. 



Near Point Wilson, in about twenty fathoms of water, were 

 found several hydroids. Possibly correlated with the paucity 

 of the latter material is the fact that but three or four Pycno- 

 gonida were seen during the entire summer. Gaprella is more 

 than abundant in some districts about Hood's Canal. Fennatula 

 was taken while fishing for Ghivisera in Discovery Bay from 

 fifty fathoms of water, also in shallower water by the dredge. 

 The sea pen, Verrillia, is to be found in the same locality.

This inlet, better known as Scow Bay, was oftener dredged 

 than all the other places taken together on account of its 

 proximity and unlimited resources. It shows several instances 

 of restricted distribution, in the area covered on Puget sound, 

 notably several transparent and one very large, orange-red 

 tunicate, and the slimy-tube annelid Siphonoi^toma. This worm 

 seemed to occur in a layer along the somewhat muddy 

 bottom, for bushels of this jell^'-like mass exclusively were 

 brought up from a region half an acre in extent. As may be 

 seen on the chart of the Hydrographic Surve}^, the depths 

 and bottoms are very variable. This is further evidenced 

 by the sharply defined faunal areas. The sandy hard bottoms 

 furnish holothurians and crabs, and the shelly bottoms are cov- 

 ered with Cynthia colonies interlaced with Spirographis tubes. 

 Two specimens of species Synapta were found here, two species 

 of Gribrella, two species of Solaster and, in the shallower water, 

 five fathoms, the four or five species of Aste7Has, common in lit- 

 toral collecting, were dredged. Many small ophiurids of two or 

 three types were gotten here, although Ophioglypha was found 

 in twenty fathoms in Discovery Bay. Among the mollusca 

 dredged in Scow Bay are one or two specimens of the large 

 scallop Amusium caurinum, numerous Gryplochiton sfelleri, 

 whose papillose dorsum is alwa^^s more or less covered with 

 mud. This is to be contrasted with other Ghilons dredged just
