76 FOSSIL ECHINI OF THE WEST INDIES. 



furrow and lateral petals, and it differs from loveni in the same characters. 

 It differs in the furrow, petals, and general shape from subcylindricus, to 

 which species Guppy referred it as a synonym; in fact, it is closer to 

 clevei, as mentioned, than it is to subcylindricus, so that perhaps Guppy 

 made a lapsus calami in this comparison.

This species, known from a number of European localities, is also 

 recorded from the West Indies. Cotteau refers to it specimens from the 

 "Miocene" of Matanzas, Cuba, Cotteau collection. A. Agassiz lists this 

 species from the "Miocene" of Anguilla.

The following is an extract from the original description of this species : 

 Species of medium size, very obliquely sloping anteriorly, subcordiform; 

 marked posteriorly by an attenuated carina. Posterior face . truncate 

 subvertically, lower face rounded on the borders, slightly swollen. Apical 

 disk excentric posteriorly. Anterior furrow narrow, very deep, with high 

 ridges on the borders, while reduced toward the ambitus, it extends as 

 far as the peristome. Anterior ambulacrum III straighter and longer than 

 the others, having the poriferous areas much less developed than the interval 

 which separates them. The paired ambulacra are deeply excavated, wide, 

 unequal; the anterior II and IV are subflexuous, divergent; the posterior 

 ambulacra I and V are shorter, rounded at their tips, having the poriferous 

 areas wider than the interval which separates them. The peristome, periproct, 

 and a part of the fascioles are not visible in the fragmentary specimen. 

 Height, 27 mm. ; length, 40 mm. (this is the length of this individual 

 specimen, but as it is very imperfect posteriorly, another specimen might 

 naturally give different proportions) ; width, 39 mm. Ambulacrum III is 

 in a very deep furrow ; the paired ambulacra are also in deep depressions ; 

 the petals of ambulacra II and IV measure 15 mm. in length, but I and V
