12 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



In the Hancock Expeditions it was found at numerous stations from 

 Oregon to Peru and the Galapagos Islands, from the shore line down to 

 about 30 fathoms. 



Aetea recta Hincks, 1861 

 Plate 1, fig. 2 



?Hippothoa sica, Couch, 1841:102. (Unidentifiable.) 

 Jetea recta, Hincks, 1880:6. 

 Aeteaslca^Osburn, 1914:186 ; 1927 :1 24. 

 Aetea ska, Marcus, 1937 : 28. 

 Aetea recta, Osburn, 1940 :346. 



Resembling A. angutna in appearance, but the "head" is narrower and 

 the whole erect portion is straighten The operculum is set more trans- 

 versely across the end of the tube and the basal portion is annulated with 

 the fine "punctations" like the stalk. 



Couch may have had this species, but as Hincks points out (1880:7, 

 footnote), the description was drawn from an imperfect specimen, which 

 is entirely unidentifiable and Couch placed the species in the genus 

 Hippothoa. 



A. recta occurs on the coast of Europe from Norway southward and 

 on the eastern American coast it has been reported from the Tortugas Is- 

 lands, Florida and the Caribbean Sea (Osburn), and from the Bay of 

 Santos, Brazil (Marcus). It seems not to have been noted on the Pacific 

 side of the Americas. 



Hancock Stations: 325-35; 333-35; 545-36; 1012-39; 1271-41; 

 1281-41 and 1295-41, from the islands off southern California, the Gulf 

 of California and Galapagos Islands, from the shore down to 80 

 fathoms. Also from the San Juan Islands, Puget Sound, Dr. J. L. 

 Mohr, collector. 



Aetea truncata (Landsbo rough), 1852 

 Plate 1, fig. 1 



Anguinaria truncata Landsborough, 1852:288. 



Aetea truncata, Robertson, 1905 : 246. 



Aetea truncata, O'Donoghue, 1923:16; 1926:40. 



Aetea truncata, Hastings, 1930:702. 



Aetea truncata, Osburn, 1947 :8. 



The erect tubules are straight, truncate at the tip and vary widely in 

 height. Both the erect and basal portions are very delicately "punctate," 

 but lack entirely the minute annulations of anguina and recta.
