Two dead specimens were taken at Camp 39, M. & M. R. R., and 

 two near the Guajara-Assu Falls; four living specimens taken on

 were sent from the Goeldi Museum. 

 Euglandina n. sp. ? 



At Camp 39, M. & M. R. R., three specimens were taken which 

 seem to differ from all South American species, but which were too 

 young to warrant a name and description. 



STREPTAXID^. 



Genus STREPTAXIS Gray. 



Streptaxis deformis Ferussac. 



Helix deformis Ferussac, Hist. Xat. Moll., pi. 32, a, fig. 1.

Seventeen specimens were taken at Itacoatiara, only a few mature, 

 streptaxis comboides laevigata C)rbigny. 



Streptaxis comboides Orb., var. laevigata Orbigny, Voyage dans I'Amerique 

 Meridionale, Mollusques, p. 234, 



Two dead, immature specimens were taken at Abuna, Bolivia, 

 and two mature and one immature at Camp 46, M. & M. R. R. 

 This species has heretofore been known only from Orbigny's descrip- 

 tion. He procured his type of the var. Icevigata from the Mission of 

 San Jose, Chiciuitos Province, Bolivia, nearly 200 miles from these 

 locations. Our specimens are a slightly smaller race (diameter 

 S, instead of 10 mm.), with the tooth of the outer lip a little less 

 prominent than would seem to be called for by Orbigny's descrip- 

 tion, but they almost surely fall into this variety, 

 streptaxis subregularis Pfeiffer. 



Philippi Abbild. II, 13. p. 127. Trvon, Man. Conch. (2), I, p. 68, pi. 12, 

 figs. 16-18. 



One mature and two immature specimens were taken on the 

 Maranguape Mountain at an altitude of about 500 ft. and two mature 

 specimens, "from the State of Ceara, " were sent by Mr. Rocha.
