Bullus Montfort, Conch. Syst., 1810, 2, p. 330. Type B. ampulla L. 
Bullaria Rafinesque, Anal. Nat., 1815, p. 142; new name for Bulla Linné. 
Bullea Blainville, Malac., 1825, pp. 477, 626; not of Rafinesque, 1815. 
Gondole Latreille, Fam. Nat. Regne Anim., 1825; German edition p. 171 (not Cym- 
bium, as stated by H. and A. Adams, 2, p. 16). 
Vesica Swainson, Malac., 1840, p. 860; not of the Mus. Calonnianum, 1797. 
Linné 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. Cossmann's reference to Klein, if we are to consider pre-Linnean 
authors, we must carry the name half a century further back and give his due to 
Rumphius. 
Bullus Montfort, 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-Linnean nomenclature, his Bullarius has no 
standing and doés not exclude Rafinesque'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. For the 
latter with Bulla abyssicola Dall, as type, I propose the sectional name of 
LEUCOPHYSEMA. 
Bullaria (Leucophysema) morgana Dall, n. sp. 
Plate 11, figure 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, concavely arcuate, callous, and reflected. Lon., 5.5; 
max. diam., 4.0 mm. 
U. 8. S, “ Albatross," station 3399, off the Gulf of Panama, in 1270 fathoms, 
hard bottom, temperature 362.04 F. U.S. N. Mus. 123,082. 
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 this part of the collection than to refer to his paper. 
Bulletin of the Museum of Comparative Zoölogy, 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 Zoologische Jahrbuch, 
3, Suppl. 4, 1898, entitled “Die Opisthobranchier der sammlung Plate,” and 
comprising 100 pages and six platos.
