Mr. Wood has determined this species as Sc. ina^quidens 

 Gervais, but I do not believe that this determination is right, 

 and although the description of Gervais is very incomplete or 

 incertain, yet his original specimen is said to exist in the museum 

 at Paris, and so we may be sure that at some time this same 

 specimen will be more completely described, and then Gervais' 

 name will be attached to another species and not to that of 

 which I am here treating. Therefore it might be better to alter 

 the name at this time, and so I propose the name of Scolopendra 

 Wootlii in honor of Dr. Wood, the first man who has made it 

 clear how much the species of Scolopendra vary in the greater 

 part of the characters, which we have been accustomed to be- 

 lieve to be the most characteristic.
