Bidlus Montfort, Conch. Syst., 1810, 2, p. 330. Type B. ampulla L. 



Bullaria Rafinesque, Anal. Nat., 1815, p. 142; new name for Bulla Linne'. 



Bullea Blainville, Make, 1825, pp. 477, 626 ; not of Rafinesque, 1815. 



Condole Latreille, Fam. Nat. Regne Anim., 1825 ; German edition p. 171 (not Ci/m- 



Hum, as stated by H. and A. Adams, 2, p. 15). 

 Vesica Swainson, Malac, 1840, p. 360 ; not of the Mus. Calonnianum, 1797. 



Linne first used the name Bulla for a subgenus of Gryllus (Orthoptera) and 

 only subsequently applied it to a mollusk. The latter use, therefore, cannot pre- 

 vail. As for M. Cossmaun's reference to Klein, if we are to consider pre-Linuean 

 authors, we must carry the name half a century further back and give his due to 

 Rumphius. 



BuUus Moutfort, must be excluded by the same rule which is invoked against 

 Cylichna. The next name in order of date is Bullaria of Rafinesque. Dumeril's 

 quadrinomials being excluded as non-Liunean nomenclature, his BuUarius has no 

 standing and does not exclude Rafiuesque's name, which is accordingly adopted, 

 the more readily as it recalls the more familiar Bulla of authors. 



Among recent Bullaria two groups may be readily noted, the large brownish 

 mottled forms from shallow water like B. ampulla L., the type of the genus, 

 and the small, white, or nearly white species of the deep-sea fauna. Tor the 

 latter with Bulla abi/ssicola Dall, as type, I propose the sectional name of 

 Leucophysema. 



Bullaria (Leucophysema) morgana Dall, n. sp. 



Plate 11, ttgure 4. 



Shell small, yellowish-white, short-ovate ; apex perforate, showing about half a 

 turn of the involved spire ; summit rounded, smooth ; surface smooth except for 

 more or less evident lines of growth and about twenty-two spiral incised lines, 

 strongly punctate, between the summit and the anterior end ; these lines are nearly 

 equidistant and a little less deep on the periphery of the whorl than toward the 

 extremities ; outer lip gently arcuate forward, thin, simple ; body with a thin 

 white callus; pillar short, coucavely arcuate, callous, and reflected. Lon., 5.5; 

 max. diam., 4.0 mm.

All the Nudibranchs and a part of the Tectibranchs, Gastropteron, and Marse- 

 niidae, having been sent to Doctor Rudolph Bergh of Copenhagen, it is not neces- 

 sary to do more in regard to tliis part of the collection than to refer to his paper. 

 Bulletin of the Museum of Comparative Zoology, 25, number 10, entitled " Die 

 Opisthobranchien," comprising 110 pages and twelve plates, October, 1894. 



Further information on the mollusks of these groups derived from this general 

 region will be found in the paper by the same author in the Zoologischc Jahrbuch, 

 3, Suppl. 4, 1898, entitled "Die Opisthobrauchicr dcr sammluug Plate," and 

 comprising 100 pages and six plates.
