 Hyponota sloping toward the sole of the foot, and smaller than its greatest 

 width. Head small, tentacles long and conical. Mantle borders smooth 

 and inclined to be directed upwai'd. 



Average size: Length 26 mm., breadth 27 mm., height 14 mm. ; 

 graetest widtht of the foot sole 13'2 mm. 



Mantle sculpture. — The mantle is entirely covered with very small 

 granules. Small and fine papillae are irregularly placed over the middle 

 field, but at the mantle borders are more closely and compactly arranged. 

 The largest pa[)ill8e possess retractile points, bearing from thi-ee to foui" 

 eyes, and ai'e sui'rounded by smaller papilhv, all of which art> dnrker than 

 the ground colour. .

Position of openijif/s. — The anus is situated on an anal jiajiilla partlv 

 protected by the tail of the foot. The respii-atorv opening in the median 

 line is closer to the anal papilla than to the mantle border by one-fifth o\' 

 the distance.
