XJuring a sojourn in Florida in the years 1892—93 J collected 

 cray-lishes from difFerent parts of the conntry. Since, on coming 

 home and with the help of the literature classifying my spe- 

 ciraens, I found three difFerent species in my collection. Two 

 of these were normal-eyed forms which have been described 

 before and are well known. They lived in creeks, small lakes 

 and ponds, very often hiding in the rich vegetation there or 

 under logs, boards and so on. Sometimes I found them digging 

 holes on the shore, at low water, and then those holes often 

 went down to such a depth that the water came up into them. 

 These normal-eyed forms were the following. Cumharus 

 fallax Hagen and Cambarus Älleni Faxon. As both of them 

 have been well described before, I have not much information to 

 add, except to mention the localities where I have found them. 



Cambarus fallax Hagen. 



Of this I collected specimens in the sulphursprings at 

 Lake Jessup and in St. John's river, in Lake Eola, in Fern- 

 creek at Orlando Orange Co. 



All my specimens except one have the posterior part of the 

 carapax shortened so that the distance from the hinder edge 

 to the cervical groove is a little less than half the distance 

 from that groove to the tip of the rostrum, sometimes very 

 little less though, and never less than %, 



Cambarus Alleni Faxon. 



This seems to be a form largely distributed in South 

 Florida. I have specimens from Hillsborough, Orange and De 

 Soto Counties. The specimens from Hillsborough County were 

 caught in a little creek and the males all belonged to the 

 »second form.; this was in October. When living-they had a
