320 APPENDIX, BULIMULUS. 



ticola Doer. (p. 191) ; and its analogue in the Cordillera is B.nivalis 

 Orb. (this Vol., p. 72). 



Doering gives no varietal name to this form in the " Informe 

 Oficial," but it is apparently what he refers to as var. azulensis in 

 the later publication quoted above. Whether the species is a Lis- 

 soacme or a typical Bulimulus I do not know. 



B. AGUIRREI (Doering). 



Shell rimate, ovate-conic, oblong, rather thin, shining ; whitish- 

 corneous, covered with a pellucid brown-corneous cuticle; striae 

 close, irregular, rugose, sometimes variegated with brownish ; spire 

 ovate-conic, the apex rather acute ; whorls 5 2, a little convex, the 

 last whorl scarcely half the length ; suture generally subcrenulate ; 

 aperture oblong-ovate ; peristorne simple, thin, acute ; the right mar- 

 gin regularly arcuate, columellar margin narrowly reflexed. Alt. 

 24, diam. 12; alt. of aperture 13, width 7-8 mill. (Doering). 



Sierra de la Ptedra Movediza; Sierra Tolosa, Argentina (Holm- 

 berg). 



Eudioptus aguirrei DOER., Actes Acad.Nac. Ciencias en Cordoba, 

 v, p. 112, pi. 2, f. 2 (1884). 



Allied to an elongated variety of B. apodemetes, and to B. men- 

 dozanus according to Doering. The plate is lacking in our copy of 

 the volume in which it is described. May be a Lissoacme. 



B. MONTEVIDENSIS Pfr. (p. 68). 



Add to synonymy: Bulimus gelidus REEVE, Conch. Icon., pi. 

 76, f. 553 (August, 1849), described as from " Central America?" 

 Mr. E. A. Smith, from an examination of the type, considers it 

 probably identical with the Montevideo variety (Biol. Centr. Amer.' 

 Moll., p". 251). 



B. POLYMORPHUS (p. 28). Reference should be made to pi. 4, 

 not pi. 5. 



B. EXILIS EYRIESII Drouet (p. 39). First reference to plate 

 should read : PL 12, figs. 53, 53 ; not 52, 53. 



B. TENUISSIMUS Orb. (p. 64). Omit " pi. 10, figs. 91, 92," and 

 supply : pi. 14, figs. 9, 10. 



Genus DRYMJEUS Albers. 



D. NAVICUL.A (p. 186) var. LATERITIUS n. v. 



Light red-chestnut, becoming pink on the spire and white toward 

 the apex, without bands, except that the base has a blackish stripe
