Tellina arctata (Conrad) var. juana Reagan. 



Tellina arctata (Conrad) Reagan, p. 186, pi. 2, figs. 16, 16 a., 



1909. 

 Tellina arctata, var. juana Reagan, p. 186, pi. 2, fig. 17, 1909. 



The specimens are all internal casts of which that designated 

 as variety juana is closest to Conrad's type of arctata. It is prob- 

 able that the differences all lie within the range of individual 

 variation. 



Tellina oregonensis Conrad. 



Tellina clallamensis Reagan, p. 186, pi. 2, fig. 18, 1909. 



The type specimen is a defective internal cast, apparently 

 referable to Conrad's species. 



Spisula albaria Conrad. 



Mactra gibbsana (Meek) Reagan, p. 187, pi. 2, figs. 19 aJ>., 1909. 

 This specimen, an internal cast, seems referable to an adoles- 

 cent Spisula albaria. 



Panope a brupta Conrad. 



Panopea generosa (Gould) Reagan, p. 188, pi. 3, fig. 20, 1909. 



The specimen exhibits both valves, one imperfect the other 

 intact. The draughtsman has selected the imperfect one for 

 figuring. The perfect valve agrees exactly with Conrad's type 

 of My a (= Panope) abrupt a. 



Teredo sp. indet. 



Teredo sp. Reagan, p. 188, pi. 3, fig. 21, 1909. 



The specimen is a mass of small nearly straight tubes, appar- 

 ently of Teredo, with a diameter at the aperture of about a milli- 

 meter and a half. 



Xylotrya ? sub striata Conrad. 



Teredo bulbosa Reagan, p. 189, pi. 3, fig. 22, 1909. 



This is identical with Conrad's species. The "bulbs" are the 

 proximal ends of adult tubes formed when the borer has com- 

 pleted its growth. 



Dentalium I sub striatum Conrad. 



Dentalium snbstriatum (Conrad) Reagan, p. 189, pi. 3, fig. 23, 

 1909. 

 The type consists of short pieces from the anterior end of a 

 large thin Dentalium, showing only incremental sculpture. The 

 specific identification is uncertain.
