 oms off Cape Borda, 3 perfect, 17 good; in 60 fathoms off 

 Cape Borda, 8 very poor ; in 90 fathoms off Cape Jaffa, 2 

 very poor; in 110 fathoms off Beachport, 3 very good, 12 

 poor; in 130 fathoms off Cape Jaffa, 1 good, 8 very poor; 

 in 200 fathoms off Beachport, 1 poor. It would seem to live

 others. 



Mitromorpha alba, Petterd. Var. axiscalpta, var. nov. 



It has the shape of M. alba, Petterd, but has crowded 

 axial incisions granulating the spirals. It has also three 

 spiral rows of small, square brown spots on the body-whorl ; 

 one just below the suture, but not on the first spiral as in 

 some of the typical i)/. alba; a second starting just above the 

 aperture and winding round to just above the middle of the 

 labrum ; a third beginning just above the two nodules on 

 the labium and running over the back of the snout. The 

 upper two rows appear in the spire-Avhorls. Sometimes the 

 shell is flamed with very light-brown between the spots axi- 

 ally. 



Dredged in Gulf St. Vincent, 10 good, 2 poor; in 55 

 fathoms off Cape Borda, 10 good, 37 poor; in 110 fathoms off 

 Beachport, 6 poor.
