outside the mouth of the ba^', such as Mopalia, Eatherina, 

 Tonicella, etc., which come up attached to stones, and always 

 clean, indicating their habitat to be a clean stony bottom. 

 Gastropteron and Bulla were thus obtained, a species of Cari- 

 nella, and a large red dendroccelous turbellarian, procured only 

 by the dredge. 



The rocky channel at the outlet of Scow Bay furnished two 

 very interesting crabs. Here the tide runs very swiftly and 

 only hardy or well protected creatures can find lodging. Crypto- 

 lithodes is a small crustacean with enormously developed lateral 

 sides of the carapace. When clinging to rocks, his resemblance 

 to Chiton or Crepidula is ver}' striking. It is a rather rare crab, 

 Stimpson's figure having been made from a single dried specimen 

 from Monterey. A smaller type was gotten from Neah Bay. 



Marrowslone Point, Hood^s Canal. 



Just south of the Marrowstone, the rockj' and sandstone bot- 

 tom is covered with Serpula tubes. The handsomest Serpula 

 builds a hard white tube, while in dark colored tubes lives 

 another variety with Lepidonotus and a bilateral hermit-crab 

 commensal. We should also mention several white Thyone-like 

 holothurians dredged here in the honeycombed sandstone. 



The upper part of Hood's canal was found to be too muddy for 

 successful dredging. Off Seabeck Dentalium was taken, but the 

 principal denizen seems to be a small species of Bulla. 



A large living Balanus tintinnabulum (?) with beak two 

 inches in diameter was taken from the bottom of Port Town- 

 send Harbor. Yery probably it was scraped from the bottom 

 of some ship l3'ing at anchor here. An Octopus but ten or 

 twelve inches long was taken off Marrowstone. Unfortunately 

 it escaped before identification. 



From various of the above named stations, the following 

 mollusca were dredged : Donax sp., Astarte (two species) 

 Cardita sp., Cardium sp., Leda sp., Pectunculus subobsoletus, P. 

 sp., Modiola modiolus, Placuanomia macroschisma, Eulima dis- 

 iorta,Eu.s]i.,Odostomiamucr'iformis, Galerus, Crepidula adunc a, 

 C. lingulata, Natica and Lunatia, Argobuccinum Oregonense, 

 Oliveita boetica, Pteronotus sp., Chrysodomus dims, Trichitropis 

 cancellatum, Bittium filosum, Ilagarita pupilla, Doto sp., Procto- 

 notus sp., Elysia viridis. Also Terebratella transversa. 



With the exception of Cardium and Lunatia the above forms 

 were found nowhere but in the zones reached by the dredge, i. e., 

 were not obtained in the littoral zones. Numerous empty shells 

 and tests properly littoral come up in the dredge, e.g., Cardium.
