GENUS 126. BAXTERIA, H.V.H., 1893. 



Valve very elongated, with median portion 

 subrhomboidal, very gently attenuated up to 

 the apices, which are inflated-rounded, with 

 punctate subareolate structure. Girdle face 

 flattened, showing numerous elongated spines, 

 which edge the valve. The two apices 

 terminated by a species of cap, large, very 

 projecting, with strong puncta.

I have dedicated this very curious and strongly marked genus to my kind 

 and learned translator, Mr. Wynne E. Baxter, as a slight evidence of my 

 recognition of all the trouble he has taken, and the sacrifices he has made, in 

 the publication of the English Edition of this work. 



Baxteria Brunii, H.V.H. Characteristics of the genus. 

 Length of valve, 5 to 5.5 c.d.m. Breadth at the median portion about 

 1.5 c.d.m. 



Fossil, Cambridge Estate, Barbadoes (E. Weissflog). 



In the unique preparation in my possession of this interesting form, the 

 valves were disarranged and placed aslant, rendering it difficult either to 

 design or photograph. Before attempting to return it (which I ultimately 

 succeeded in doing) to a convenient position for photographing, and which 

 attempt, if unsuccessful, might have caused its destruction, I solicited my 

 friend Professor Brun to assist me, with his great talent as a draughtsman, in 

 order that a satisfactory representation of it might be produced, and I have 

 therefore felt it but my duty, while thanking him for his kindness, to dedicate 

 the species to him. The figure in the margin, therefore, is a combination of 

 the drawing of Professor Brun and the photograph which I subsequently 

 made of it.
