of the Balearic Islands. 343 



Besides the above, some fragmentary remains consisting of a few 

 land shells and a small piece of bone embedded in the typical red 

 matrix were found in a coast cave east of the mouth of the Santa 

 Galdana Barranco. These no doubt indicated the former existence of 

 an ossiferous deposit. 



Two of the deposits, JS'os. 4 and 5 in the list, were situated in low 

 cliffs and were but a few feet above the sea. So little remained of 

 either that their former condition could only be surmised as that of 

 cave-deposits. The few bones left appeared to be those of Mi/otragtis. 



In only one instance (No. 6) were ossiferous remains found actually 

 in a cavern. This was in the Cueva de los Extranjeros, so called from 

 the neighbourhood of some deserted barracks, a relic of the British 

 occupation ; this cavern is situated in the cliffs between the mouth of 

 the Santa Galdana Barranco and the small bay of Marcaria. It faces 

 the sea, from which it is only separated by a few yards of sloping rock. 

 Most of the single chamber was roofed and ran in for a distance of about 

 84 feet, the width being 15 to 20 feet and the height 25 to 30 feet. 



At the entrance the lioor was heaped with irregular blocks of stone, 

 doubtless the result of incursions by the sea. The inner 18 feet 

 were covered by a sloping sandy deposit, which, at one point, rose to 

 within 8 feet of the roof. Its face had fallen away, leaving a section 

 exposed, and this showed that tlie uppermost layer, 1 to 2 feet thick, 

 contained a quantity of mammalian {Myotragus) remains accompanied 

 by land shells. The entire deposit, including the ossiferous band, had 

 evidentlj' been introduced into this chamber by means of water which 

 had found a way through a channel in the rock. The opening of this 

 was found at the apex of the cave ; it was choked with stalagmite, 

 and a number of bones were also present here. The originally much 

 greater extent of the cave breccia was indicated by the presence of 

 land shells enclosed in red matrix at a considerable distance from the 

 present deposit. Similar indications were observed in a second and 

 larger cavern lying a little to the east of the one just described. 



Three ossiferous deposits which had undoubtedly been accumvilated 

 in fissures in the limestone rock were found near the coast of the 

 Bajoli district, north of Ciudadela. The cliffs in places rise to 

 a considerable height, 200 feet and more, and this promontory, like 

 a great pai't of the Miocene coastline, is edged by a barren strip of 

 the much-weathered limestone. Here and there this was covered by 

 long strips or sheets of stalagmite Avith occasional bases of stalagmitic 

 columns. 



One of the deposits (No. 2) was in a small crevice on the cliff face 

 and near its summit. The red matrix contained a mass of small 

 remains, including those of a dormouse, two shrews, etc. The two 

 other fissure deposits were situated on the neighbouring farms of 

 Sestrucarias and Torre Vieja, and were very similar; both lay parallel 

 to the edge of the cliffs at a distance of perliaps a hundred yards 

 and within the barren border mentioned above. Likewise both were 

 intersected by a narrow gully leading to the sea. In each case there 

 remained but the merest remnant of the original deposit, which barely 

 retained anywhere a thickness of a foot, and in many places only 

 sufficient matrix was present to contain a thin section of bone.
