Porphyrobaphe iostoma (Sow.), white variety and occurrence of some- 
thing like varices, P. saturnus (Pfr.), fresh specimens yellowish green, 
P. debar ghice (Reeve) = gloriosa (Pfr.), P. Jcelletti (Reeve) = fang air inoi 
(Hidalgo), with a characteristic red spot without epidermis at the base 
of the last whorl, and P. fraseri (Pfr.), size variable ; Dohrn, JB. mal.

Bulimulus. II. Strebel, Mex. Land Conch, v. pp. 45-48, distinguishes 
couchologically 6 sections and 11 subordinate groups, each exemplified by 
sevoral species, and adds that anatomically his three first sections, 
exemplified by B. berendti (Pfr.), schiedeanus (Pfr.), and proteus (Brod.) 
\_Leptomerus and part of Scutalus, Albers], are decidedly distinct from the 
three following, exemplified by B. sulcosus , chiapasensis , dombeyanus , 
droaeti, attenuatus, ptaivanus, nigro-fasciatus , and knorri (Pfr.), lobbi 
(Reeve), totonacus , and palpalaensis (Strebel) [parts of Scutulus , Mormus, 
Drymceus and Otostomus , Albers], the former having jaws composed of a. 
few strong plates, and the radula resembling that of Bulimus and Euca- 
lodium, the latter jaws composed of numerous thin plates, and the radula 
quite peculiar. [The former seem to correspond to Bulimulas as 
restricted by the Recorder, Binnenmoll. Venezuela, 1873, or Orthoto- 
mium of Crosse & Fischer, 1875, the latter to Otostomus , Martens, 1873, 
or Goniognathinus, Crosse & Fischer, 1875.] General notes on their 
anatomy ; Pfeffer, ibid. pp. 49-55.
