Cephalopoda and Pteropoda 11b 



Spiratella pacifica Dall? 



This genus is more generally known by the name of Limacina. The minute 

 young specimens in the collection, perhaps from being preserved with formalin, 

 have lost their shelly matter, and it is impossible to say whether they belong 

 to the Pacific type or to the better known and much more common Atlantic 

 species S. helicina Phipps.

Spiratella from the surface. (F.J.) 

 Station 9a. Latitude 55° 02' N., longitude 144° W., June 27, 1913. With marine 



Plankton, numerous larval or very young specimens mixed with young 



Clione. (F.J.) 

 Station 12a, /. Latitude 54° 38' N., longitude 157° 45' W., June 30, 1913. 



Water temperature 50°. 7 to 51°. 3 F. One Spiratella with many young 



Clione, from at or near the surface. (F.J.) 

 Station 13a, /. Latitude 54° 30' N., longitude 159° 42' W., July 1, 1913. Water 



temperature 47°. 5 to 48°. 1 F. Many Spiratella at or near the surface. 



(F.J.) 

 Station 15a, /. Latitude 55° 22' N., longitude 165° 45' W., July 3, 1913. Noon 



to 3 p.m. Many Spiratella. (F.J.) 

 Station 20a. Grantley harbour. Port Clarence, Alaska, July 30, 1913. Several 



Spiratella from the surface. (F.J.) 

 Station iOd. Off Bernard harbour, Dolphin and Union strait, June 8, 1915. 



Depth of water nine fathoms, temperature 32° F. Six vertical hauls through 



a hole in the ice to five fathoms depth, produced several veliger larvae of 



Spirqtella. (F.J.) 

 Station 46fc. Off west end of Chantry island, in Dolphin and Union strait, 



June 10, 1916. Depth of water about eight fathoms, the temperature 



32° F. A vertical haui through four feet of ice to depth of five fathoms 



produced several veliger larvae of Spiratella. (F.J.).

 The lack of lateral symmetry is probably due to contraction in the preservative medium.
