Hippocrepina indivisa, Parker, 1870, in Dawson’s paper, ‘ Canadian 
Naturalist,’ n. s. vol. v. p. 176, fig. 2. 
This is an exceedingly interesting arenaceous type. The 
test is long, tapering to a point at the inferior extremity, 
broad and rounded at the superior end. The aperture is at 
the centre of the broad end, and is irregular in shape, often more 
or less curved so as to resemble a horseshoe. The shell-wall 
is thin, finely cemented, and smooth externally ; the cavity of 
the shell is undivided. In colour it is brown at the inferior 
extremity, lighter near the apex. Length of full-sized speci- 
mens about 1:0 millim.; those from the Matyushin Shar are 
somewhat smaller. _ 
Hippocrepina indivisa was originally found by Dr. G. M. 
Dawson in Gaspé Bay at a depth of from 16 to 20 fathoms 
(29 to 36 metres), and has since been dredged by the Rev. 
A. M. Norman in deeper water off the coast of Norway.
