-New York to the Arctic Ocean; on the northern coasts of Europe 

 south to- Great Britain. Off Stonington, Connecticut (A. E. V. and D- 

 C. Eaton) ; Vineyard Sound (Y. N. Edwards) ; Portland, Maine (C. B. 

 Fuller). 

 The synonymy of this species has been greatly and unnecessarily con 

 fused. The Clio retusa of Linue was a southern Pteropod, having a tri- 

 quetral shell. In a foot-note on page 1094 of the twelfth edition of the 

 Systema Naturae, he states that he had not seen the genus 0/io, but 

 adopts it from Brown. He gives three species mentioned by Brown, all 

 having shells. 



THECOSOMATA. 



STYLIOLA VITBEA Yen-ill. Plate XXY, fig. 178. (p. 443.) 



American Journ. Science, vol. iii, p. 284, Plate G, fig. 7, 1872. 



Shell smooth, polished, diaphanous, almost glassy, long conical, rather 

 slender, slightly curved toward the acute apex; animal white ; locomo 

 tive organs obovate, with the end broadly rounded, and bearing 

 slender tapering tentacle-like processes near the middle of the anterior 

 edge; intermediate lobe short, rounded in front. 



Length of shell, 11.5 uim ; diameter, 2&quot;&quot;&quot;. 



Taken among Salpcc, off Gay Head, Martha s Yineyard, in the after 

 noon, September 9, 1871. 



Several other species of this and other related genera were taken by 

 Messrs. S. I. Smith and Oscar Harger, off Saint George s Bank, in 1872, 

 on the United States steamer Bache. These may occasionally occur 

 also in the vicinity of Nantucket and Martha s Yineyard.
