The next Melanellid to be cited is one referred to but not named by 

 von C. Hartlaiib, who in his Report on the Dredging Operations off 

 the West Coast of Central America to the Galapagos, to the West 

 Coast of Mexico, and in the Gulf of California, in charge of Alexander 

 Agassiz, carried on by the U. S. F'ish Commission steamer Albatross 

 during 1891, Lieut. Commander Z. L. Tanner, U. S. N., commanding,' 

 calls attention (p. 147, pi. 4. fig. 25) to a "StyVfer {Mucronalia) para- 

 sitic upon a crinoid found in the Gulf of Panama." This is named by 

 Dr. W. H. Dall in 190S. 



In 1899 Edward G. Vanatta published a paper on West American 

 Eulimidae * in which he described the following : 



Eulima lowei Vanatta, page 254, plate 11, figures 9, 10. 



Eulima historta Vanatta, pages 254-5, plate 11, figures 7, 8. 



Eulima compacta Carpenter, pages 255-6, plate 11, figures 11, 12, 



Eulima randolphi Vanatta, page 256, plate 11, figures 13, 14, 



Eulima micans Carpenter, pages 256-7, plate 11, figures 1, 2. 



Eulima rutila Carpenter, plate 11, figures 5, 6. 



Nine yeai-s later the present writer published A New Parasitic 

 MoUusk of the Genus Eulima.^ In this Eulima ptilocrinicola Bartsch 

 is characterized. 



The year following Dr. William H. Dall * bestowed the name 

 Stilifer (Mucronalia) bathymetrae upon the moUusk mentioned by 

 Hartlaub in 1895. 



In the same year he published his Descriptions of New Species of 

 MoUusks from the Pacific Coast of the United States with Notes on 

 other Mollusks from the same Region.^ On page 253 of this paper 

 he describes Eulima {?) lomana Dall. 



The 3'^ear following William H. Dall and the present writer published 

 A Monograph of West American PyramideUid Mollusks.^ On page 

 230, Odostomia (Scalenostoma) rangii De Folin is described and 

 figured. This is now transferred to the family Melanellidae. 



In 1912 the present writer referred to Odostomia (Scalenostoma) 

 rangii De Folin on page 342 ; he also described and figured Odostomia 

 (Scalenostoma) babylonia Bartsch (pp. 287-288, pi. 38, fig. 3) of his 

 paper on Additions to the West American PyramideUid MoUusk 

 Fauna, with Descriptions of New Species,^ which must now be 

 referred to the family here discussed. 



The last paper dealing with West American Melanellids was pub- 

 lished by Frank M. Anderson and Bruce Martin on Neocene Record
