60 r August, 



Order o£ the Telostei or osseous fishes, wliich includes the majority of 

 existing forms. 



No remains of the Amphihia have been discovered ; but the 

 Reptilia are represented by a great number both of existing and ex- 

 tinct forms, the latter including the Iguanodon and Teleosaurus, as well 

 as Plesiosatirus and Ichthtjosaurus, and several species of Pterodactyls. 



Very few traces of the birds of the period have been preserved in 

 the Cretaceous strata of Europe; but in North America their remains § 

 have been discovered not uncommonly. 



As the Mammalia had existed in the preceding Period they were 

 probably represented by numerous species, no traces of which have, 

 however, yet been detected. 



The plant life of the earlier portion of the Cretaceous Period 



closely resembled that of the Jurassic in the predominance of ferns, 



cycads, and conifers ; but before the close of the Period there appears 



to have been a rapid development of new forms — including a number 



of true Angiosperms, and various Monocotyledons — closely allied to 



existing types.

DESCEIPTIONS OF SOME NEW SISTERIB^E {COLEOPTERA) IN 



GENEEA HITHEETO EEPEESENTED BY SINGLE SPECIES. 



BT GEORGE LEWIS. 



SpATIIOCHTJS MEEIDIANUS, 11. sp. 



Ovalis, convexus, rufo-hrunneus, nitidus. Elytris striis 1 — 4 et suturali 



integris, 2 posterioribus basi arcuatim punctatis, 5 pa/mm abbreviato. Propy- 



gidio pygidioque sparse punctatis. Long. If lines. 



Hab. : Zanzibar. 



This species is more convex than 8. Coyei, Mars., with the thox'ax 

 less dilated at the sides, but in the punctuation generally it closely 

 follows Marseul's species. My specimen was captured by M. Eaffray. 



MOJS'OPLIUS PINGUIS, n. sp. 

 Sub-ot'bicularis, supra valde convexus, nigro-cupreus, strigosim dense punc- 

 tatus. Elytris seriebus septem punctorum Icevium, nitidorum, striis nullis. 



Long. 4 lines x 3. 

 Hab. : Cape of Good Hope. 



The curious strigose punctuation of this species agrees with that 

 in M. injlatus, but is rather larger ; the rows of smooth spaces on the 

 elytra resemble in a remarkable manner the markings of Chrysomela 

 suhcenea, Mots. The type of this species is in our national collection, 



§ Sevei-al birds have been discovered by Prof. Marsh from New Jersey and Kansas.
