in the Province of Granada. 371 



by a hill composed of red sandstone, containing a thick bed 

 of gypsum, resting upon greywacke, and capped by secondary 

 nummulite limestone, a considerable semicircular open space is 

 crossed that slopes down from the more retired mountainous 

 district to a horizontal flat contiguous to the shore. In the higher 

 part of this open tract several patches were observed, composed 

 of beds of soft marly sandstone, and of arenaceous marl, full of 

 pectens ; but they are insulated, and without continuity for more 

 than twenty or thirty yards. Another patch of the upper tertiary 

 deposit was observed in ascending from this tract to the Convento 

 San Anton, situated at the base of a high hill of nummulite 

 limestone, characterised by two projecting peaks. This is the 

 most elevated patch of the tertiary formation I have met with in 

 the immediate neighbourhood of Malaga, and it contains many 

 perfectly preserved shells of the Cardium genus, identical with 

 those now found in the land of the Port of Malaga. The sec- 

 tion 5. Pi. -II. will give an idea of the situation of this fragment 

 of tertiary origin, the line of section being nearly from south to 

 north, and intersecting, in the first part of its course, a group of 

 hills called Los Cantales, formed of nummulite limestone, resting 

 upon red sandstone, in which the open tract above alluded to 

 terminates towards the east. 



In this patch-like manner httle fragments of the tertiary order 

 continue to be seen along the line of coast between Malaga 

 and Velez-Malaga, on the slope of the mountainous district to 

 the Mediterranean shore ; but, before reaching the latter town, 

 which is twenty miles distant from Malaga, there is a more con- 

 tinuous little tract belonging to this formation which will soon 

 be noticed. 



The last locality in the vicinity of Malaga I shall cite, where 

 beds belonging to this superior part of the tertiary formation, or 

 to group 2, hav6 been observed, is about two miles from the 

 town, up the Rio Guadamedena, and they may be traced for a 

 couple of miles farther into the mountainous district towards the 

 north. They appear to be the discontinuous prolongation of 

 those stated to form the higher part of the tract contiguous to 

 Malaga, where excavations have been made in the subjacent ar- 

 gillaceous deposit for brick -earth, and contain ostrcre, balani, and 

 pectens, like the former.
