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 

 deha of C. and F. (1893) and typical lindcni), 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- 

 color) of C. and F. 



(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 lindeni 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 tennis becomes the specific 

 name. H. vernalis Morelet (Test. Nov. I) appears to be 

 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 

 Pfeififer's name. The same is true of //. amoena Pfr. and H. 

 purpnreo-fiava Morelet, and of H. ozveniana Pfr. and H. coc- 

 cinostoma Mo. 



Lucidella (Poenia) lirata (Pfeififer) (1847). — Eighty-one 

 specimens in and at edge of pools, on ground, in lowland jungle 

 (H, I, a, or H, v, a). This species appears almost semi- 

 aquatic, and is often found together with aestivating Pisidium, 

 Planorbis, etc. |
