There is some doubt about the identification of many forms in Ehrenberg's works, 

 especially in his Mikrogeologie, bearing a close resemblance to this Bpecies. It seems 

 to me unwise to load the Bynonymy with names assigned by him to forme the 

 character of which it is now impossible to discover. Those given above arc probably 

 specimens of this Bpecies. It is a question whether A. senarius Ehrenb. and .1. 

 8edenarius Ehrenb. 6 belong hen- or under A. aplendena (Shadb.) Kali'-. If their char- 

 acter could !)'■ clearly determined their assignment to either of these Bpecies would 

 call for a change of the Bpecific name. I Look upon the question as far too obscure to 

 warrant such a chang 



Many wide varieties of this Bpecies were found in these investigations. Those from 

 Btation 2823 have the marginal processes on alternating segments, and bo protruded 

 beyond the usual marginal curve as to give the valve an angular form. A variety 

 from station 2807 approaches close to A. tri/urcatus Temp. & Br.c 



Found at Matn.ii> 2807, 2823, 2835, 2848, 2851, 2859, 2860, 2882, 3346, 3603, 3604, 

 3671, 3691H, 3694H, 3712H, W13H, 1014H, W29H, 1585H, Galapagos Islands to 

 Bering Sea, and off Honshu [aland, Japan. 



At Btation 3604 in the Bering Sea occurs the variety called "monterey" bj
