finds that the evidence of an ancestral connection between certain 

 of these halolimnic genera (namely, Typhobia, Bathanalia, Limno- 

 trochus, Chytra, Paramelania, Bythoceras, Tangnnyicia, Spehia, and 

 Nassopsis) is not nearly so strong as was anticipated from the 

 inferences already drawn by Mr, Moore ; nevertheless, a fairly good 

 prima facie case for the originally marine origin of these exceptionat 

 organisms has been made out by Mr. Moore, but the supposed 

 connection, in long ages past, of Lake Tanganyika with an arm 

 of the Jurassic sea is held to be highly improbable, if not wholly 

 impossible. In the second place Mr. Hudleston has collected together 

 much of the scattered evidence as to the geological history of this 

 vast Lake-area, some of which had escaped Mr. Moore's notice, 

 especially the works of Professor Cornet of Mons, M. Barrat, and 

 Mr. Molyneux, etc. 



From a geiieral consideration of the case it is apparent that the 

 great longitudinal faults, folds, furrows, or " graben," as they are 

 named, in which Tanganyika and the other lakes lie, are not older 

 than the Tertiary period, and cannot therefore have formed a refuge 

 in Secondary times for the remnant of an old Jurassic marine fauna 

 in its hollows. Indeed, it seems probable that a large portion of 

 the elevated interior region (composed of Archaean, Granitoid, and 

 other ancient rocks) may have been a land-area from Triassic times 

 or even earlier. 



A magistrate and a landed proprietor in Dorsetshire and the 

 West Riding of Yorkshire, Mr. Hudleston is a keen sportsman, 

 loving both fishing and shooting, and divides his time between his 

 country house at West Holme, near Wareham, Dorset, and his town 

 residence, and still enjoys the meetings of the Geological, the 

 Geographical, and other Societies, in the work of which he feels 

 the same enthusiasm as of old.
