Two specimens from S waff ham. 



Frondicidaria striga, sp. n. (Fig. 1.) 



Lateral outline of test subovate, acuminate ; the oral end 

 more produced ; complanate, with the surface nearly even, 

 but relieved by two strong riblets running vertically down 

 the middle of the test and covering the oral terminations of

each chamber. The margins of the chambers not marked 

 by very strong shell-thickening as in some species having 

 the same general outline. Edge of the test slightly grooved. 

 The shell-surface under a high power aj)pears finely granu- 

 lated or ripjjled. Length of ty])e specimen 1'9 milliin. ; 

 breadth 1*4 millim.; thickness of edge *133 millim. 



This species appears to be quite distinct from any pre- 

 viously figured. In outline it somewhat resembles F.perovata, 

 Chapman *, but is not so regularly ovate^ and the sutural 

 margins of the chambers are not incurved towards tiie aboral
