Lriguus is frequently broken as the result of falling, and many specimens 

 extensively repaired are found. One from near Planter, Key Largo, which had 

 broken the spire and lost several pieces of the shell is drawn in fig. 8. 



VII. DESCRIPTIONS OF THE COLONIES OF LIGUUS. 



1. Pure Colonies of Liguus crenatus. 



Lriguus crenatus (Swains.) was originally collected in Cuba by a brother of 

 the noted naturalist William Swainson. It is found in the northern part of 

 Havana Province, from near Havana eastward. 15 In Cuban crenatus the green 

 lines are narrow and usually about equally distributed on the upper and lower 

 parts of the last whorl. The ground is white throughout, never yellow on the 

 last whorl; and the columella is thin and simple, not truncate below in adults; 

 the shell is thin and light; whorls 7 to 7J^. The name was taken from the 

 circumstance that there is a slight notch in the lip-edge at the termination of 

 each green line. A copy of Swainson's original figure has been given in the 

 Manual of Conchology, XII, PL LVIII, fig. 80, and a typical Cuban specimen is 

 shown in PL LVIII, fig. 81. 



No specimens exactly resembling Cuban crenatus have been found in Flonda, 

 although in some the deviation is very slight. The presence of yellow coloring 

 is a distinctively Floridan trait. 



L. crenatus has usually been considered a variety of fasciatus on account o 

 its association with fasciatus forms in the hybrid colonies of the east coast 

 It seems however, both in Cuba and Florida, to be otherwise so distinct a stock 



that it may well be treated as a "species." It is a more evolved race than 

 fasciatus, having lost all brown or other longitudinal (axial) color-marking, an 

 especially by the loss of pink coloring, which is a remarkably constant— in iac 

 invariable— character of L. fasciatus and of its Cuban allies L. blmnianus ana 



tt The entire range of L. crenatus in Cuba is not known, but specimens from near Havana, ar en 

 and Sancti Spiritus are before me. At Matanzas I found typical L. fasciatus but no erenow-
