toises higli, and an ammonite seven inches in diameter, in 
the Montana de Santa Maria, north-north-west of Caripe. 
I nowhere saw the limestone of Cunianacoa (of which I 
treat specially in this article) resting on the sandstone of 
the Llanos; if there be any such superposition, it must be 
found on descending the table-land of Cocollar towards the 
Mesa de Amana. On the southern coast of the gulf of 
Cariaco, the limestone formation probably covers, without 
the inter|)oaition of another rock, a mica-slate which passes 
to carbui ettcd clay-slate. In the northern part of the gulf 
I distinctly saw this clayey formation at the depth of two 
or three fathoms in the sea. The submarine hot springs 
appeared to me to gush from mica-slate like the petroleum 
ot Maniquarez. If any doubts remain as to the rock on 
which the limestone of Cumanaeoa is immediately super- 
posed, there is none respecting the rocks which cover it, 
such as (1) the tertiary limestone of Cumaua, near Punta 
Delgada, and at Cerro de Meapire ; (2) the sandstone of 
Quetepe and Turimiquiri, which, forming layers also in the 
limestone of Curoanaco, belongs properly to the latter soil; 
the limestone of Caripe, which we have often identified in 
the course of this work, with Jura limestone, and of which 
we shall speak in the following article. 
VIII. POBMATION OF THE COMPACT LIMESTONE OF 
Caripe. — Descending the Cuchillo de Guanaguana towards 
the convent of Caripe, we find another more recent forma- 
tion, white, with a smooth or slightly couchoidal fracture, 
and divided in very thin layers, which succeeds to the bluish 
grey limestone formation ol Cumanaeoa. I call this in the 
first instance the limestone formation of Caripe, on account 
of the cavern of that name, inhabited by thousands of noc- 
turnal birds. This limestone appeared to me identical (1) 
with the limestone of the Morro de Barcelona and the 
Chimanav Islands, which contains small layers of black 
kieselschiefer (slaty jasper) without veins of quartz, and 
breaking into fragments of parallelopiped form ; (2) with 
the whitish gi-ey limestone with smooth fracture, of Tisnao, 
which seems to cover the sandstone of the Llanos. Wo find 
ice formation of Caripe in the island of Cuba (between the
