The considerable color variation, which seems not to be cor- 
related with the habitat, may be classified as follows: 
(a) General coloration: milky-white to yellowish (variety 
delta of C. and F. (1893) and typical linden), greenish (most 
common), and chestnut-brown. 
(b) One broad, brown stripe from near the greatest ventri- 
cosity up to the suture (variety epsilon of C. and F.). 
(c) Two broad, brown stripes, with a light stripe between ; 
the second below the greatest ventricosity includes varieties 
zeta and etta chiapensis (when combined with the brown body- 
Colom) motC.vand sh 
(d) Two dark and one light band above the greatest ventri- 
cosity; the stripe of class (b) divided through the center 
(variety gamma of C. and F.—typical tenuis). 
Helicina lindent and H. tenuis were described in the same 
paper (P. Z. S. 1848; April 25, 1849). The former name has 
page priority, but von Martens (1890) chose to regard the 
former as a form of the latter, so tenuis becomes the specific 
mame. de vernahs Moreleh\(lest Noval) appeanse tome 
prior as regards date of publication of the name, as his paper 
bears the date Feb. 15, 1849. However, H. vernalis, like so 
many of the names in the Test. Nov., is only recognizable 
because later redescribed and figured, so it seems best to retain 
Pfeiffer’s name. The same is true of H. amoena Pfr. and H. 
purpureoflava Morelet, and of H. oweniana Pir. and H. coc- 
cinostoma Mo. 
Lucidella (Poenia) lirata (Pfeiffer) (1847)—Kighty-one 
specimens in and at edge of pools, on ground, in lowland jungle 
(H, 1,:a, or H, v, a).* This species appears almost semi- 
aquatic, and is often found together with aestivating Pisidium, 
Planorbis, etc.
