158 PROCEEDINGS OP THE ACADEMY OF [March, 



I have not seen specimens. Mr. Binney in his first note considers the 

 Salmon river form identical with what Mr. Simpson reported as H. 

 fimbriatus from Indian Territory, and gives no separate or definite 

 description of it, though he mentions that Hemphill had given the 

 (MSS.) name "salmonacea." The figure of one of the original speci- 

 mens, given in Binney's Fourth Supplement, represents a shell with 

 wide umbilicus and small aperture, like H. arizonensis, from which it 

 differs, according to published information, by the smoother surface, 

 arizonensis being constantly very well sculptured. 



Punctum pygmaeum (Drap.). 



San Marcos, Hays county; Comal county; Hondo river, Medina 

 county; Devil's river, Val Verde county. 



The form in this region is slightly larger than northeastern speci- 

 mens, and is more strongly sculptured. There are barely four whorls, 

 the first H smooth, the next striate; the last two whorls have striae 

 at regular intervals much larger, with about six fine striae in each space, 

 and the basal spirals are very distinct. This sculpture reminds one 

 of the west coast forms, conspectum, pasadenoe and calif ornicum, which 

 however are decidedly larger and coarser shells of a dark brown color. 



SUCOINEID^. 

 Succinea luteola Gld. 



Gould, Proc. Bost. Soc. N. H., Ill, p. 37, June, 1848 (Texas); Terr. Moll., 

 II, p. 75, pi. 67c, fig. 1. (Florida; Texas, especially Galveston.) Bin- 

 ney, Terr. Moll., V, p. 419; Man. Amer. Land Shells, p. 441. 



Succinea texasiana Pfr., Monogr., II, 526; Roemer's Texas, p. 456, 1849 

 (Galveston). 



Succinea lutescens Sowerbv, Conchologia Iconica, XVIII, pi. 10, fig. 67 a, b, 

 1872 (Texas). 



We took specimens in Texas along the Guadalupe river above New 

 Braunfels, Comal county; San Antonio, Bexar county; near Hondo 

 river about two miles north of Hondo, Medina county, and in Val 

 Verde county at Del Rio, high land west of Devil's river, and in the 

 canyon of the Pecos near the High Bridge. 



In Gould's original description the only locality given was Texas. 

 In the Terrestrial Mollusks he states "found in Florida, and more 

 abundantly in Texas, especially in the region of Galveston." Speci- 

 mens collected at Galveston by the author in 1885 agree perfectly 

 with Gould's figures, and that place may be taken to be the type 

 locality. I have seen no Florida shells which I would refer with cer- 

 tainty to luteola, though *S. floridana is closely related.
