THE NAUTILUS. 43 



Leptinaria living st on ensis (Hinkley). In front of the hotel, 

 on the hillside.

 nearly buried in the soil.

 crossed by the telegraph line. A few fossils were taken at 

 this place. 



Neritina listeri (Pfr.). Same place as above. 



MOUNTAINS OF Eio CAVECH and those back of Cavech vil- 

 lage. These are listed together, although there is some dis- 

 tance between. The village is a little farther up the coast 

 than the mouth of the river, the stream having a course 

 oblique with the coast. The mountains or hills of this region 

 are often steeply sloped and covered with thick timber, which 

 keeps down the undergrowth in a great measure, so one can 

 climb without much interference from that source. These 

 limestone hills have many small crevices or openings, afford- 

 ing protection to different kinds of animal life besides mol- 

 lusks.

 village than elsewhere. See NAUTILUS, Vol. 33, page 79.
