nothing in the fauna of the Oomia Trigonia-beds to contradict the 

 results reached by a study of the Uitenhage Mollusca, and a con- 

 sideration of all the available evidence seems to justify the conclusion 

 that here also we are dealing with the part equivalent of the 

 Neocomian in Europe. 



(c) Traces of a Belated Fauna in the Godavari District and in 

 Hazara. Traces of the Uitenhage-Oomia lamellibranch-fauna, as 

 principally indicated by the presence of Trigonia ventricosa, have 

 also been found to occur in an outlier of the Tripetty beds about 

 24 miles north-east of Coconada near the south-east coast of the 

 peninsula of India. * Trigonia ventricosa is said to be here 

 accompanied by Trigonia smeei, a characteristic fossil of the 

 Oomia Group in Cutch, though it seems possible that this may be 

 T. crassa, an Oomia form of similar type.f The small collection 

 of fossils from near Coconada was examined and named by Stoliczka, 

 and it comprises Inoceramus and a few other lamellibranchs as well 

 as Helicoceras and other remains of cephalopods. 



Trigonia ventricosa has also been recorded from strata exposed in 

 the Margalla Pass in Hazara (N.-W. Himalayas), where it is said to 

 be found in profusion.} The bearings of these occurrences in a dis- 

 cussion of the broad question of distribution will be considered below. 



(d) Neocomian in German East Africa. The Lower Cretaceous 

 fossils collected during W. Bornhardt's journeys in German East 

 Africa (1895-1897), and described by G. Muller, are of special 

 interest in the present connection, because they exhibit in some 

 measure a Uitenhage facies and also furnish strong links with the 

 molluscan fauna of the Oomia Group. The remains of Cephalopoda 

 are unfortunately very scanty and again fail us as a basis of com- 

 parison, but important links are found in some of the lamellibranchs, 

 which include well- characterised Trigonia. Foremost amongst these 

 is Trigonia ventricosa, occurring at a locality '8 km. north of the 

 Nkundi stream, 29 km. north-west of Kiswere, in strata ascribed to 

 the Lower Neocomian and brought into correlation with the Uitenhage 

 beds by Dr. Miiller. Trigonia beyschlagi G. Miiller, which here 

 accompanies T. ventricosa in great abundance, appears to have no 

 counterpart in the Uitenhage beds, but it clearly belongs to the same 

 category of modified Costatae as T. smeei \\ and T. crassa 1i from the
