The species is named in honor of Dr. Henry Allen Moe, Secretary 
General of the John Simon Guggenheim Memorial Foundation. 
Bulimulus coagulatus (Reeve) 
Bulimus coagulatus Reeve, Conchologia iconica, vol. 5, Bulimus, pl. 77, fig. 558, 
1849. 
Bulimulus (Bostryx-Lissoacme) coagulatus Pilsbry, Manual of conchology, ser. 
2, vol. 10, p. 161, 1897. 
Type locality: Lima, Peru. 
The embryonic sculpture of the protoconch in this species is not 
smooth as in Bostryx or Lnssoacme, but is obliquely waved as in 
Bulimulus. 
Bulimulus bonariensis morenoi Preston 
Bulamulus (Drymaeus) morenot Preston, Ann. Mag. Nat. Hist., ser. 7, vol. 20, 
p. 494, 1907. 
Bulimulus bonariensis morenoi, Parodiz, Nautilus, vol. 70, p. 133, 1957. 
Type locality: Argentina (very probably from province of Buenos 
Aires). Not a Drymaeus but a typical Bulimulus with a few inter- 
rupted microscopic spiral lines on the nucleus, not regular and con- 
spicuous as in the subgenus Scansicochlea. Preston also assigned 
other species to Drymaeus in the vague sense as used prior to Pilsbry’s 
nomenclature of 1897, which belong to different genera (e.g., chacoensis 
to Protoglyptus, nigroumbilicatus to Peronaeus). The type specimen 
of morenoz is shorter and more solid, yellower, and more polished than 
the common bonariensis (=sporadicus). The variations of this species 
deserve further study. 
Under the name Siphalomphix bonariensis I have found an original 
description by Rafinesque (Atlantic Journal and Friend of Knowledge, 
no. 5, p. 165, 1833), as follows: 
Siphalomphiz N.B. Shell conical, opening oval acute, rounded, columella twisted 
with a tubular ombilic [sic]. It differs from Agathina by the columella and the 
ombilic. S. bonariensis or Ag. bonariensis Raf. Six spires tip nearly obtuse, 
first spire with a transversal angle—shell about one inch, semi-transparent, 
brittle. 
The locality of the specimen is given in the title of the article, “New 
genera of land shells from Buenos Aires, South America.” 
Although this diagnosis is rather ambiguous, as are many others of 
the same author, it is possible to recognize from it the Bulimulus sporad- 
icus bonariensis Strobel, 1874, which is the only form from that area 
with same proportions and color. No other true Bulimulus is found 
near Buenos Aires. Rafinesque’s publication antedates by 2 years 
that of d’Orbigny’s Bulimulus sporadicus (originally Bulimus) which 
has been in use since 1835. Therefore, the typical sporadicus sporad- 
icus d’Orbigny, which is a northern form, is a subspecies of bonariensis
