lEEDALE : ON NAMES OF BRITISH MARINE MOLLDSCA. 337 



p, 73, 1880, proposed for 0. nitens, Jeffreys, is added as a sub-genus 

 for its type species alone. DolieUa has thus priority, but Dall and 

 J^artsch separate these, making DolieUa a sub-genus, and admitting 

 Bracliystomia as a section only of Odostoynia, s.str. Whatever the 

 ultimate status, the name must be changed on account of the prior 

 Brachystoma of many authors and even in Molluscs of Gardner, Geol. 

 Mag., ser. iir, vol. iii, p. 160, 1876. 



In the List appear Brachystomia rissoicles (Hanley) and B. amhigua 

 (Maton & llackett) = pallida. In the first case, as a varietal name, 

 is cited mtida, Alder. 



Odostomia rissoides was proposed by Hanley in the Proc. Zool. Soc, 

 1844, p. 18, which appeared in July, while 0. nitida was introduced 

 by Alder in the Ann. Mag. Kat. Hist., vol. xiii, p. 326, pi. viii, fig. 5, 

 on May 1, 1844, and the latter has therefore absolutely priority. 



Maton & llackett ])roposed Valuta ambigua (Trans. Linn. Soc, 

 vol. viii, p. 132, 1807) as a new name for Turho pallidum, Montagu, 

 Test. Brit., pt. ii, p. 325, 1803, and when it is acknowledged that 

 the latter is indeterminable, the former must also be so classed. 

 In La Feuille des jeunes Nat., ser. v, jS'o. 493, January 1, 1912, 

 Martel discussed T. pallidas, Montagu, and concluded that, in view 

 of the diverse attempts at identification and the facts cited, it must be 

 regarded absolutely as indeterminable. Asa substitute he advocated 

 fulimoidcs, Hanley, which was proposed at the same time and place 

 as rissoides. He discussed this latter, and relegated it to varietal 

 rank only under eiilimoides. He did not concern himself with nitida, 

 Alder, so that his nomination must be reconsidered, even if his facts 

 be accurate. However, Forbes & Hanley (Hist. Brit. Moll., vol. iii, 

 p. 284, 1853) cite Odostomia scalaris, Macgillivray (Hist. Moll., 

 Aberdeen, p. 154, 1843) as a synonym of 0. rissoides, Hanley. This 

 name is even earlier than nitida, Alder, and its claim must be 

 investigated. Jeffreys ignored it, as he lurai)ed the majority of the 

 Byramidelloid shells under Odostomia, and consequently Philippi's 

 Ilelania scalaris (Enum. Moll. Sicil., vol. i, p. 157, pi. ix, fig. 9, 1836) 

 was earlier. The latter species, however, is the type of Pyrgisculns, 

 which, if not admitted as a valid genus, is ranked under Turlonilla. 

 Apparently scalaris \vould replace rissoides, and eulimoides come into 

 use for ambigua. 



BCRKILLIA, n.g. 



I introduce this name for Odostomia fenestrata, Jeffreys (Ann. Mag. 

 Nat. Hist., ser. ii, vol. ii, p. 345, November, 1848 (ex Forbes MS.) : 

 Dartmouth). This species is included in the List under Pyrgulina, 

 whicli is obviously an unhappy location. Dall & Bartsch place it 

 under lnrbo7iilla, giving it subgeneric rank under the name Tragula, 

 which Monterosato (Xomen. gen. e spec. Concli. Medit., 1884, p. 86) 

 provided for it alone. That name cannot, however, be maintained, as 

 there is a prior Tragulus, Brisson, Keg. Anim., 1762, p. 65. 



EvALEA, A. Adams. 

 Dall & Bartsch replace Ondina, Folin, by the above name, which 

 was proj^osed as a sub-genus of Odostomia (Ann. Mag. Nat. Hist.,
