Habitat. — Mediterranean and Canary Islands. 



This Mediterranean form appears to me to differ sufficiently 

 from the more northern A. sulcata to warrant its specific distinc- 

 tion. Its smaller size, more triangular form, decidedly feebler 

 ribbing, richer brown colour, not unfrequently varied with rays of 

 a paler or darker tint are characters parting it from that species.
