 Subgenus Katadysas Mihi. 



Characters. Eyes eiglit, suhequal^ in two rows, both curved 

 doivnivards ; fang of the cheliceres articulated downwards; 

 palpi inserted near the extremity of the maxillce. Feet If. 1. 2. 3. 

 Pulmonary orifices only two. 



Observations. This very anomalous spider, found only once, 

 offers a very striking instance of the manner in which nature 

 combines characters, so as to separate widely animals Avhich are 

 apparently closely allied. This has all the essential characters 

 of Mygale, but one (having but two pulmonary orifices), and 

 yet it is obviously related to Lycosa, near which it should be 

 placed in a natural arrangement. I know nothing of its habits, 

 except that it dwells or hides under stones. It probably makes 

 no web. 



Habitat. Alabama.
