behind ; hinder margin obtusely, and rather obliquely, truncate, the supero-posteal 

 portion completely rounded off, infero-posteal portion the most produced, but 

 without any sign of angularity ; rostrate process as in C. norvegica, but projected 

 fm-ther forward over the antennal sinus ; lower margin of that sinus arcuate from 

 the base, and at the same time sloping slightly backwards, as it unites in a bold 

 curve with this ventral margin ; valves white, pellucid, glabrous (or nearly so), and 

 shining ; seen from above the form is elongated-ovate, greatest breadth central, 

 and equal to half the length ; length, 2*3 mm. ; breadth, 2 mm. The eye 

 is very large ; "the appendicular branch of the antennae is very short, nodiform, 

 ending in a long seta ; the penultimate joint of the mandibular palp is very 

 narrow ; the third pair of following limbs has the vibratory lamina margined with 

 fom'teen ciliated setse, the five posterior of which are separated from the preceding 

 by a short interval ; caudal laminse of usual form furnished with eleven finely- 

 toothed ungues." 



Very rare at Utne, in the Hardanger Fjord, in 40—50 fathoms (Gr. O. 

 Sars). The shell has been described from a specimen kindly sent to us by Professor 

 Sars.
