58 THE NAUTILUS. 



1907, when a large part of the Bureau of Fisheries collection in 

 Dr. Verrill's charge was turned over to the U. S. National Museum, 

 and bears the legend, " Sta. 770, Figured, T. intert-upta Totten," in 

 Dr. Bush's handwriting. The name Turhonilla pseudointerrupta 

 Bush, is therefore superfluous. 



Dr. Bush states that Odostomia hushiana Bartsch, is preoccupied 

 by Odostomia bushiana Jeffreys, 1884. 1 have been unable to find 

 any such name. The only reference to bushiana by Jeffries in 1884, 

 that I know, is to TurboniUa bushiana Verrill. 



I am not in position to give any opinion upon what Dr. Bush's 

 young shell from Woods Holl may be, but I do know that our shell is 

 an Odostomia belonging to the subgenus lolcBa. lolcea, like Menes- 

 tho, from which it is distinguished by having an umbilicus, is quite 

 variable in its strength of sculpture. Odostomia (loleza) hendersoni 

 Bartsch, is neither the type species nor the norm, of lolcea, but comes 

 well within its definition. It does not belong to the same family to 

 which Aclis belongs. 



A single specimen of Phasianella sulcosa Mighels, was found by 

 Mighels in Casco Bay. It was described in 1843, Bost. Journ, Nat. 

 Hist., IV, p. 358, PI. XVI, f. 4, and later doubtfully referred to 

 Rissoella by Stimpson. It is quite probable that it really belongs to 

 Menestho, the subgenus of Odostomia, which it resembles in sculp- 

 ture, but no plication is shown or mentioned on the columella, and 

 nothing is said of the nucleus. The lack of positive data concerning 

 these characters kept me from referring it to the Pyraraidellidae. 



I would be pleased to know upon what grounds Dr. Bush bases 

 her contention of the synonymy of Phasianella sulcosa Mighels, and 

 Odostomia (^Menestho) sidcata Verrill ; for Mighels' description and 

 figure are entirely different from Professor Verrill's description, and 

 Dr. Bush's figure of Odostomia (Menestho) sulcata Verrill. 



Phasianella sulcosa Mighels, is represented much more inflated 

 than Odotto77iia (Menestho) sidcataVerriU. P. sulcosa Mighels, has 

 three incised spiral grooves between the sutures on each whorl, and 

 three or four on the base, while Odostomia (Menestho) tulcataYer- 

 rill is represented as having five spiral grooves between the sutures 

 and nine upon the base. A glance at the two figures alone is enough 

 to convince one that they are not at all specifically related, and this 

 deduction is verified by the description. I do not believe that the 

 author of the latter species would agree to have his species put under
