1. LiTHAU^A NODULOSA, Buucan. Plate XIX, Figs. 4, 5. 



, The corallum is in the shape of short stunted branches, which are covered with 

 irregularly quadrangular shallow calices with thick perforate walls. The shape and 

 size of the calices is irregular, and the septal distribution also, there being from 20 to 

 30 stoutish septa. There is a small or rudimentary columella in some calices, whilst it 

 is long in others. The calices are crowded. 



Height of corallum 2 inches. 



Breadth of calices to to ^ inch. 



Locality. Near Raduk, ten miles S.E. of Jhangara, Nari series. Survey-number

List of the Species of Fossil Corals which are found in the Nari Series of Sind, 

 and which are identical with those found in other localities. 



Trochocyathus cyclolitoides, M. Ed. & J. Haime. Also in the Nummulitic deposits 

 of the Pyrenees and S. Giov. Ilarione. Eosazzo in Friuli. 



Stylophora pulcherrima, D'Achiardi, Common at Eosazzo in Friuli. 



Trochosmilia varicosa, Eeuss. In the Oligocene of Crosara. 



Styloccenia Taurinensis, M. Ed. & J. H. At Eonca, S. Giov. Ilarione, and in the 

 Miocene of Turin, Eivalba, &c. 



Cycloseris Perezi, M. Ed. & J. H. Gap ; Nice ; Faudon, St. Bonnet (Hautes-Alpes). 



There are 20 species of Fossil Corals in the Nari series, and one of them is found 

 at a higher horizon. Of these, one quarter are found in the Upper Nummulitic and 

 Oligocene deposits of Europe. 



Hence the examination of the specimens of Corals from the Eanikot, Khirthar, 

 and Nari series of Sind yields 76 species and several varieties.
