1840.] Carboniferous Stratum at Baypoor. 239 



Above of a light brown colour, lightest on the rump ; wings and tail 

 dark brown ; chin, throat and breast, pale brown ; belly, vent and under 

 tail coverls, white. 



Length 4$ inches; wing 31; taillJ^ths; wings reach £ an inch 

 beyond tail, which is very slightly forked ; tarsus T \ths ; bill to front 

 T Vhs. 



264.— #. riparia, L ?.— New species ? 



This Swalloiv I venture to place (though with hesitation) under the 

 European species, as I see it is enumerated in Franklin's Catalogue. 

 It differs from the last named species, chiefly in its larger size, lighter 

 coloured wings and tail, whitish throat, and in the rump being of the 

 same shade of colour as the back. 



Length 4f 3 wing 4 ; tail 2 ; sligtly forked ; tarsus hardly T ^ths ; 

 feathered on the back down to the hind toe. 



I have hitherto only seen this species on one or two occasions in the 

 neighbourhood of Jaulnah. It was on both occasions single, but flying 

 in company with other swallows (ff. Jeivan and H. filifera) in the 

 close neighbourhood of water. 



II— Account of a Carboniferous Stratum at Baypoor near Calicut 

 Malabar Coast.-By Lieut. T. J. Newbold, 23rf Light Infanty* 



In consequence of having observed some carbonaceous bits of clay 

 in the bed of the river at Baypoor, a sea port town about 6 miles south 

 from Calicut on the Malabar coast, in lat. north 10° 11', and long, east 

 75° 53', I took a canoe and proceeded up the river in order to exam 

 me the section of the strata, its northern bank afforded. It presented 

 steep cliffs, varying from 20 to 40 feet in height, which, near tha 

 mouth of the river immediately below the traveller's bungalow con- 

 s.sted of a gritty laterite ; that further up the river passes into'a ho- 

 montally stratified loose grit or sandstone; this often becomes com- 

 pact and variegated with red and yellow bands. Beds of an ochreous 

 yellow earth tend to loosen its structure, near which it assumes a f™. 

 able, earthy, character. 



Not far from the bungalow, underlying these beds at the foot of the 

 cliffs, near the river bed, and washed by the tide at high water is a 

 seam or stratum of carbonaceous shale, passing into a black clay from
