Family TEMNOPLEURIDM. 



Gems TEMNECHINUS, Forbes, 1852. 



The great collections of the species of this genus, which we have shown to be 

 synonymous with Temnopleurus, as used by d'Archiac and Haime, came from Kachh 

 and Kattywar, and the paucity of forms in the collection of the Indian Geological 

 Survey from Sind seems to strengthen this opinion. Two new species are amongst the 

 collection from Sind, and their Tertiary Australian facies is remarkable. 



1. Temnechinus Eousseaui, d'Archiac & Haime, sp. Plate XL VII, Figs. 3 & 4. 



The reasons for placing in the genus Temnechinus, Forbes, the species described 

 and named Temnopleurus Eousseaui, d'Archiac & Haime, have been given in the 

 ' Monograph of the Fossil Echinoidea from Kachh and Kattywar,' pp. 51, 56, and 84, 

 Pal. Indica, Ser. XIV. 



A much-worn specimen of Temnechinus Eousseaui, d'Archiac & Haime, sp., is in 

 the collection from the Gaj or Miocene deposits of Sind, and it belongs to the depressed 

 variety. We have figured the shape of the part of the test which remains, and also a 

 magnified view of the ambulacral and interradial plates close to the peristome. 



Locality. Entering the hills on the road from Jangri to Biila Khan's Thana. 

 Survey-number G -<f^.

2. Temnechinus affinis, Duncan & Sladen. 



The interesting species which we described from a well-preserved specimen from 

 the Miocene of Kattywar is represented in the Gaj series of Sind. The remarkable 

 ornamentation shown in the illustrations of the species in plate xiii, figs. 11 & 12, of 

 the ' Fossil Echinoidea of Kach and Kattywar,' Pal. Indica, Ser. XIV, is indicated in a 

 worn and badly fossilized specimen from Sind. The specimen from this last locality 

 has the poriferous zones more sunken than in the type ; but this hardly seems to be of 

 classificatory value. We do not illustrate the specimen, as it is not sufficiently well 

 preserved, but simply refer to the illustration already alluded to. 



Locality. Gaj or Miocene series of Sind. Entering the hiUs on the road from 

 Jangri to Bula Khan's Thana. Survey-number G -^^. 



There is a solitary specimen of a regular Echinoid which has lost the apical disk, 

 but which otherwise is well preserved. It has the facies of Lepidopleurus (page 306), 

 but the peculiar shape of the coronal plates is not seen. On the contrary, there are
