482 K. J. Bush — Notes on the Family Pyramidellidw. 



Odostomia (Chryssalida) bushiana Bartsch (p. 99) is like 

 specimens in our IT. S. F. C. collection from shallow water off 

 Cape Hatteras, N. C. There is also a small lot from Vine- 

 yard Sound, Mass. (Not Odostomia bushiana Jeffreys, 1884.) 



The Odostomia (Iolma) hendersoni Bartsch (p. 101) is iden- 

 tical with specimens from Woods Holl, Mass., in our own col- 

 lection, identified as an immature Aolis striata Verrill, 1880. 

 Its generic affinity needs further study, as it is very doubtful 

 whether it can be related to the Pyramidellidse. As Iolma 

 (p. 101) is described as having spiral cords and axial riblets, this 

 species is erroneously referred to this subgenus, for it has but a 

 few very fine spiral incised lines. 



Odostomia (Menestho) bruneri Yerrill, 1882 (p. 102). Type 

 and only specimen is lost. 



Odostomia (Menestho) sulcata Yerrill, 1880 and 1882 (p. 484, 

 f. 2, from Georges Bank, in 45 fms.), is O.sulcosa Mighels, 1843 

 (Phasianella Mighels and Rissoella Stimpson ; Binney-Gould, 

 1870). The name morseana Bartsch (p. 104) is, therefore, not 

 needed. 



There is so great variation found among a large series of 

 specimens of Odostomia bisuttiralis Say and O. trifida Totten 

 (pp. 104-108) that it seems desirable to unite the two forms 

 under bisuturalis, with subspecies trifida; the exigua Couth- 

 ouy, 1838 (p. 106) also being a possible subspecies. The sub- 

 species ovilensis Bartsch (p. 107) is simply a very large form. 

 The subspecies bedequensis Bartsch (p. 106) is much more 

 nearly related to O. impressa Say (p. 103). In fourth line of 

 the description, axial is undoubtedly intended for "spiral." In 

 a marginal note p. 328 in Binney-Gould, 1870, Prof. Yerrill 

 has written : u Have seen shell figured (597). It is a genuine 

 O. trifida" Below, under O. trifida, he adds " Pasithea sor- 

 dida Lea (this Journal, vol. xlii, p. 110, pi. i, fig. 6) to the 

 synonymy. 



Odostomia (Odostomia) modesta Bartsch (p. 108, pi. 13, 

 tig. 50) is distinct from the O. modesta Yerrill, from Eastport, 

 Me. (p. 484, f. 8), which has flattened whorls and a somewhat 

 angular body whorl, and much more prominent nucleus. 

 Therefore it requires the new name Odostomia gibbosa, not 

 preoccupied by the Chemnitzia gibbosa Carpenter, 1857, which 

 is a Turbonilla. 



The Odostomia (Liostomia) eburnea (Pissoa and Pissoella 

 Stimpson), 1851 (p. 109) is not the same as that in Binney- 

 Gould, 1870, p. 297. Specimen, p. 484, f. 7, is from MV 

 Desert, Me., collected by W. E. Oleaveland, 1862. 



Odostomia (Odostomia) dealbata (Stimpson) (p. 108) is not 

 the same as fig. 595 given in Binney-Gould, p. 327. This, as 

 indicated in a marginal note, represents a " much larger and dif- 

 ferent species" which may be called O. Gouldii, new name. 

 F. 6 is a typical form from Yineyard Sound, Mass., 1875.
