This appears to be the most common spider of the 

 island. Mr. Oates's collection contains hundreds of speci- 

 mens, young and full-grown, and among these latter also a 

 few males. The back of the abdomen is in the adult male 

 of a brownish or dirty yellowish colour, with one or two more 

 or less distinctly limited black spots on either side near the 

 lateral angles, and sometimes also with two round paler spots 

 somewhat before the middle, as in most females *. The 

 dorsal tubercle of the female's cephalothorax is rather low and 

 obtuse, sometimes quite truncated at the tip, where it is fre- 

 quently furnished \\'\t\\ two longitudinal, very fine and short 

 furrows, but not cloven so as to form two tubercles.
