ÖPVERSIG-T AF K. VETENSK.-AKAD. FÖRHANDLINGAR 1900, N:0 8. 921 



p/iorella (piadril. JÖRGENS. Bergens Mus. Aarbog 1899 N. 2, 

 p. 12). 



Tliis species was found at one poiiit only, viz. 42° S. 3^ W. 

 in the southern Atlantic. It occurred besides in samples from 1° S. 

 27" W. and 5°— 21° N. 24' W. — The Dutch Frigate »Königin 

 pjmma» collected this species in April 1900 from 23° S. 3° E. 

 to 5' S. 17° W., thus in the Benguela Current, near St. Helena 

 and Ascension, besides in May at 1° N. 24° W. and 12 N. 32° W. 



Ampliorella (?) antarctica Cl. N. Sp. — 

 liouse thin-walled, campanulate, hyaline and 

 structureless, with a short apical spine. 

 Mouth not constricted, without distinct teeth. 

 Length 0,06—0,07, diameter 0,046 to 0,041 

 m.m. — Fig. 1. 



Some rare specimens were found in styli- 

 and tricho-plankton intermingled, from 45° S. 

 2&° E. to 45° S. 34° E. Fig. 1. 500 t. m. 



Amphorella norvegica (Clap. & Lachm.) V. Dad. Cyttaro- 

 cylis norvegica JÖRGENS, var. was found in two samples, at 45° S. 

 2^ and 29° E. As I have not seen (in water) any 

 structure of the house, I think it is more natural to 

 place it in the genus Amphorella than in Cyttarocylis. 

 The antarctic specimens were soniewhat smaller than 

 the arctic, and there was a difference in the number pjo-. 2 

 of teeth, being less close, about 14 only, on the ant- ' ™' 



arctic specimens. — Fig. 2. 



Ampliorella Steenstrupli (Clap. & Lachm.) v. Dad. — This 

 species, which occurs not rarely in the styli-plankton of the 

 northern hemisphere, was found at about 34° S. 29' E., in all 

 samples from 41° S. 6° W. to 45° S. 26° E. and at 43° S. 71 E. 



Codonella pusilla Cl. (Öfvers. K. Sv. Vet. Akad. Förh. 

 1899 N. 10 p. 970). This species was seen in samples from 

 39° S. 10° W. to 42° S. 3° W. It has been noted in the 

 northern hemisphere from 46° N. 13° W. to the Newfoundland 

 Banks.
