?Sterna8pis fossor Stimpson. 



? Sternaspis fossor, Marenzeller, Ann. K. K. Hof museums Wien, V, (1890), 

 pp. 5-8. 



As Johnson remarks, the Sternaspis from the neighborhood of Van- 

 couver Island agrees in all respects with specimens from the Atlantic 

 Coast. Stimpson's S. affinis from Puget Sound is with little doubt to 

 be considered a synonym. It is noticeable that the lateral angles of 

 the shield plate become more prominent on examples from the more 

 southern stations. As represented in this collection this species 

 attains a considerably larger size than the last, some of the specimens 

 being 25 mm. long and 9 mm. in diameter. 



Stations 4192, Gulf of Georgia, off Nanaimo, Vancouver, B. C., 

 89-97 fathoms, green mud and fine sand; 4194, Halibut Banlc, Gulf of 

 Georgia, 111-170 fathoms, soft green mud; 4201, Queen Charlotte 

 Sound, off Fort Rupert, Vancouver Island, B. C, 138-145 fathoms, 

 soft green mud, sand, broken shells; 4218, Admiralty Inlet, vicinity 

 of Port Townsend, Washington, 16 fathoms, soft green mud; 4223, 

 Boca de Quadra, southeastern Alaska, 48-57 fathoms, soft green mud ; 

 4233, vicinity of Yes Bay, Behm Canal, 39-45 fathoms, soft gray mud 

 and rocks; 4244, Kasaan Bay, Prince of Wales Island, 50-54 fathoms, 

 green mud; 4247, same region, 89-114 fathoms, green mud, sand and 

 broken shells. 



HERMELLID^.

Sabellaria cementarium Moore, Proc. Acad. Nat. Sci. Pliila., 1906, pp. 248- 

 253, PI. XII, figs. 45-51. 



This fine species is probably rather common and may possibly be 

 identical with /S. calif ornica Fewkes, though the description of the latter 

 fails in several respects to apply to this species. This point I hope to 

 clear up later. The tubes, formed of agglutinated sand grains, are 

 remarkable for their strength and hardness, and are found singly or in 

 small clumps attached to stones. 



Specimens were taken at the following stations : 4220 (type), 

 Admiralty Inlet, near Port Townsend, Washington, 16-31 fathoms, 

 green mud, sand and broken shells; 4247, Prince of Wales Island, 89- 

 114 fathoms, green mud with sand and broken shells; 4274, Kadiak 

 Island, 35-41 fathoms, green mud and fine sand; 4288, Uyak Bay, 

 Kadiak Island, 67-^9 fathoms, gray mud.
