106 THE NAUTILUS. 



The following species are also known from this locality : 



Hyalinia gundlachi, Pfr. Macroceramus unicarinatus, Lam, 



Microceramus turricula, var. perconicus, Pils. 



Melaniella acuticostata, Orb. Urocoptis camoensis, Pfr. and 



Vertigo pellucida, Pfr., which I found abundantly at Mariano. 

 In a small " higuna " near Camoa I found Ampullaria coH?crt, "Wood, 

 a Planorhis, Ancylus havanensis, Pfi-., and Physa cubensis, Pfr. 



At Guanabacoa in the Havana Province there is a vigorous colony 

 of Carocolus sagemoii, var. semiaperta. Mart., which has a curious 

 history. The species belongs to Eastern Cuba. Some fifty years 

 ago Dr. Nicolas Gutierrez, tlie founder of the Academy, and one of 

 Cuba's most distinguished scientists, put some young sagemons in 

 his garden at S. Francisco de Paula, near Guanabacoa. Tliey were 

 typical Caracolus arangiana in different colors, some with and some 

 without umbilicus. But all are now umbilicated, and correspond 

 precisely with the variety named by Martens, semiaperta (not in 

 Arango), which came originally from the Cauto river near Bayamo.* 



Cardenas and Matanzas are well worth a visit whether one has 

 visions of snails or not. Tlie former city — the fifth in size on the 

 Island* — is lOG miles from Havana by rail, and its commerce in 

 honey, mahogany and asphalt has been augmented greatly by AuiCri- 

 can enterprise. Indeed Cardenas has been called an American city, 

 though I saw fewer Americans and heard less English there than in 

 other western ports. However, the whole city turned out on Sun- 

 day to witness the increasingly popular American game — baseball. 



I heard a missionary, whose church joined hard against a black- 

 smith shop, patiently compete for a hearing with its busy anvil, and 

 just across the narrow street rang deafeningly and incessantly the 

 electric gong of a moving picture show, which form of amusement 

 has become as fully identified with Cuban life as it has outrun our 

 American taste for cheap entertainment. The beautiful Bay is very 

 ample but shallow, and lies over extensive beds of asphalt. The 

 water is almost fresh from the constant upward flow of some mighty 

 subterranean river, or perhaps from many streams flowing through 

 the limestone rock of this region. 



Here I found flourishing churches, well disciplined schools, and 



* Prof. Pilsbry considers semiaperta only a variety of arangiana. 

 *Its population is about 25,000.
