Biddulphia grandis Boyer, Proc. Acad. Phila. 1900: 706. 190B 



The necessity of chissing this as a Biddul])hia becomes evident as soon as we dis- 

 regard the unimportaid fact that it is often fouiul in triangular form. So far as my 

 experience goes^ it is (juite as abundant in sea dredgings in the (piadrate form. It is 

 the dominant species of stations 2915II to 2921IL 300811, 30I0II, 30J3H, 443011,450211, 

 and 4571IIj where it occurs in immense quantities and wil}u>ut any of the triangular 

 varieties present. H. L. Smilirs type 599 is a similor case. He marks it "Tuscarora 

 soundings S. of Sandwich Lsl. 1468 fms.," the locality, tlu^refore, corresponding almost 

 exactly with station 3008II. Five to 8-angled forms are fre<[uent in all large gather- 

 ings. But whether of triangular form or not, this species, seen from the valval side, 

 buf especially from the zijnal side, willi its horndike processes at the angles and its 

 peculiar set of the valves on the girdle, is shown to be an almost typical example of 

 Biddulphia. Like all the other members of this genus, it is either njarine or fossil,
