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 witn 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 with two longitudinal, very fine and short 
furrows, but not cloven so as to form two tubercles,
