cutting point, which shows a development corresponding to the 

 reflection, but neither of them reaches to the posterior end of the 

 base. 



A number of intermediate teeth are following, in which the 

 base is getting broader and shorter, the two cutting points stouter 

 and longer, extending beyond the base. Marginals short and 

 broad, provided with two well developed inner cutting points, the 

 outer posterior margin of the base bearing three to four small 

 teeth or being simply indented. Last marginals rudimentary, 

 quadrate, minute. 



Flammulixa crebriflammis, Pfeiffer, sp. 



In "Nautilus," vii. July, 1893, No. 3, p. 35, Mr. C. Hedley 

 published the following note : — "In the Reference List Flammu- 

 lina infundibulum, H. and J., was placed under F. crebriflammis, 

 Pfr., as a synonym. Tryon and Pfeiffer, whom we followed in 

 this course, were certainly wrong in connecting infundibulmn 

 with crebriflammis (Mon. Hel. Viv. iii. p. 148, etc.). H. i7ifundi- 

 bulum was described from Yavas, Tonga I., and appears to be a 

 small variety of gradata, Gould. It was omitted from Mousson's 

 Tongan list."
