tubercles on the shell are open to much variability 5 we 

 have specimens with only one row, some with two, and others 

 with one row on one part of the surface and two on another 

 portion of the same shell. The stria? of growth are strongly 

 marked.

There are several examples of this in the Gilbertson col- 

 lection ; and it is difficult to pick out the figured shell. The 

 descriptions by Prof, de Koninck and M'Coy are clear and 

 comprehensive. It is the 



Turbo biserialis et T. semisulcatus, Phillips (as above).

On the Shells called Turbo by Phillips. 



Turbo tiara has been placed by M'Coy in his genus Platy- 

 schisma, and has doubtless found an appropriate resting- 

 place there. T. biserialis ( = T. semisulcatus) is in want of 

 a generic receptacle ; and for it, in s 11 probability, a name will 

 have to be coined. By De Koninck it was placed in Littorina, 

 and by M'Coy doubtfully in the genus under which it was 

 described. By Meek and Worthen * it has been regarded 

 as forming a section of Naticopsis. We shall examine this 

 subject further when we take up the species of that genus in 

 the Gilbertson collection.

XLIV. — Neio Cerambycidse from Ecuador. 

 By Charles 0. Waterhouse. 



Since my last paper on Coleoptera from Ecuador I have de- 

 termined three more species of Cerambycidas from among 

 those collected by Mr. Buckley to be new, which I here de- 

 scribe. 



In the Prionidffi, the specimens of Prionacalus Buckleyi, W., 

 taken by Mr. Buckley differ immensely in size and develop- 

 ment, in the same way as is seen in P. cacicus and P. atys • 

 and the sculpture of the thorax varies also somewhat in all 

 the species. I have seen one small example of P. Buckleyi
