The original description was as follows: 



Test free, monothalamous; elongate, straight, or somewhat curved; superior or 

 oral end broad and rounded; inferior tapering to a blunt point and closed. Aperture 

 a wide curved slit, often irregular, set in a raised collar in the center of the broad 

 end of the test. Vv^alls thin and finely arenaceous; color reddish bro'wn at the point, 

 lighter toward the oral end. 



Length, about one twenty-fifth inch (1 mm.V 



Distribution. — From the available records this seems to be a 

 species of very cold waters. Its type station is Gasp6 Bay, at the 

 mouth of the St. Lawrence River, 16-20 fathoms (Dawson). It has 

 been recorded from Holsteinborg Harbor, Greenland, 10 fathoms 

 (Norman), and from soundings in the Matyushin Shar, Novaya 

 Zembya, 10-15 fathoms (Brady), and from the Bay of Kola (Schlum- 

 berger). A single specimen is known from the British Isles in the 

 Clare Island region, Ireland (Heron- Allen and Earland). 



The only material I have seen at all referable to this species is from 

 Albatross station D201S, off the eastern coast of the United States 

 in 788 fathoms, bottom temperature 39.0° F. (U.S.N.M. No. 9681). 

 Heron-Allen and Earland speak of their Clare Island specimen as 

 "light gray in color and metallic in luster, due probably to the use 

 of minute flakes of mica in the construction of the test." 



The material I have from D20i8 has also a very silvery surface, 

 which was noted at the time the specimen was first found.

Dcscripiion. — Test free, usually elongate, subcylindrical, fusiform 

 or elongate oval, consisting of a single chamber; wall thin, composed 

 of sponge spicules and fine sand, aperture rounded at the open end of 

 the test. 



As far as records show the various species of Technitella are widely 

 scattered, but do not occur in any considerable numbers. As shown 

 by Heron-Allen and Earland for T. legumen the test in that species 

 at least is composed of two defuiitc layers of spicules, those of the
