THE NAUTILUS. 11 



extra hand below the principal one should be separated from the true 

 bifasciata, in which the extra band is above. Taylor's pi. XXXIV, 

 t'. 13, may accordingly be called v. infrafasciata. At Wangen, Baden, 

 I noted that the Helix pomatia were of full size, distinctly larger 

 than >he form observed in Switzerland (Gersau, Fluelen). Observa- 

 tions on the variation of //. nemoralis and hortensis yielded nothing 

 of special interest ; at Wangen H. hortensis v. lutea with bands OUOOO, 

 123(45) and 1(23)45. At Schaffhausen H. hortensis lutea 00000. 

 At Gersau H. hortensis lutea 12345. At Fluelen H. nemoralis 

 rubella 00000. At Zurich the Arion ater was dark reddish brown, 

 with bright orange-vermillion foot-fringe. At Wangen the A. ater 

 presented the beautiful bright red var. rubra, which I had never had 

 the pleasure of finding before, but also the red-brown variety. At 

 Troyes, France, Helix fruticum was found in both the reddish and 

 whitish varieties. I was pleased to find Helicodanta obvoluta, which 

 I had never collected before, at Brugg, Switzerland. Helicigona 

 lapicida was found at Brugg and at Wangen. T. D. A. COCKERELL. 



RUMINA DECOLLATA IN TEXAS. Mr. Camp found a large colony 

 of Rumina decollata Linn, in a Brownsville, Texas, garden, and 

 succeeded in getting a few without losing the points, carrying them 

 in cotton. They are larger than my Charleston or New Orleans 

 specimens and less uniform in general architecture. The largest 

 measured 30| alt., 11 mm. diam J. H. FERRISS.
