Tectula lincta, Lows. 
Madeira, Dr. Hillebrand to Dr. Newcomb. 
The species is viviparous, 
Plebecula lurida, Lows. 
Madeira. Dr. Hillebrand to Dr. Newcomb. 
Jaw low, slightly arcuate, ends scarcely attenuated. Anterior surface with 
&bout 8 broad, separated ribs. 
Lingual membrane (Pl. I. Fig. L) with 32-1-32 teeth, of the usual Helicea 
type. It will be seen in the figures that the change from lateral to marginal 
teeth is formed with the splitting of the inner cutting point. 
Leptaxis undata, Lowe. 
Madeira. Dr. Hillebrand to Dr. Newcomb. 
The jaw is described by Mörch as narrow, with numerous ribs converging to 
centre, 
Lingual membrane of the individual examined peculiarly abnormal, the mal- 
formed teeth, as figured by me (Pl. I. Fig. E), being repeated often on each 
transverse row, and down the whole length of the lingual membrane. Such 
malformations are often found in lingual membranes, Fig. a seems to be a 
normal lateral tooth. 
Veronicella 
Mozambique. Mr. J. S. Gibbons. 
Jaw as usual in the genus ; over 22 ribs, 
Lingual membrane as usual in the genus. (See Terrestrial Mollusks of 
United States, V. 240, Pl. V. Fig. P.) 
Veronicella olivacea, STEARNS. 
Polvon, Occidental Department, Nicaragua, MeNiel. 
I am indebted to Professor F. W. Putnam for some of the original specimens 
of this species, which Mr. Stearns has also collected in California. 
The jaw is as usual in the genus, with over 20 ribs. 
The lingual membrane is also as usual in the genus, as described and figured 
by me in Terr. Moll. U. S., V. 240, Pl. V. Fig. P. 
HEMPHILLIA. 
I am indebted to Mr. H. Hemphill for specimens of Hemphillia glandulosa 
from Portland, Oregon, much larger than those first obtained by him, being in 
their contracted state over 40 mill. long. The shell is not external, as de- 
scribed from the small specimens first received (Terr. Moll. U. S., V.), but is 
quite covered by the mantle, excepting at the perforation, which is 8 mill. long 
by 5 broad. Fig. F of Pl. IT. gives an outline of this specimen.
