One unnamed Zonites bears considerable resemblance to Z. lima- 

 tulus, but is of only three mm. diameter, more depressed, sutures 

 less impressed and outer whorl more rounded, and having four 

 whorls. 



The other unnamed one has the general size and appearance of 

 Z. arboreus, but has six whorls. These were both found on the 

 Boston Mountains. Zonites brittsi was described in the Nautilus 

 of last January. The type specimens were collected by Mr. R. A. 

 Blair, of Sedalia, in Garland County near Hot Springs. They are 

 very close to Z. demissus. 



Patulu solitaria has not before been recorded from as far south. 

 Very few specimens of Pohjgyra texasiana were found in the State, 

 but they were very abundant in the Indian Territory across the 

 river from Fort Smith. In no county except Garland were both 

 dorfeuilliana and its variety sampsoni found. The latter was 

 most abundant in Carroll County, fifteen or twenty being frequently 

 under one stone. P. jaeksoni Avas much larger than typical size on 

 the bluflTs at Van Buren. But one T. obstricta was found, and that 

 a dead one, near Batesville. T. edentata were collected on the Bos- 

 ton Mountains in Franklin County. They are larger than inflecta 

 and almost or entirely without teeth on the peristome. T. fallax, 

 from the northwest corner of the State, were quite small, and many 

 of them albinos.
