248 RECORD OF SCIENCE FOR 1886. 



Etheridge, Robert, Jr., aud P. Herbert Oa.rpenter— Continued. 



Phauioschismci, E. & C, 13S-3. Type PunlatreniaUtcs acuta, G. B. Sby. There 

 appear to bo three species iu the Carboniferous rocks of America. ? Pentre- 

 mites {Cadaster) Kentuckiensis, Shuiiiard, and two species from New Mexico 

 ■which Mr. Wachsuinth will describe. 

 II. Subfamily Crypto^cMsmidce, E. & C, 1888. 



Orophocriuus, von Secbach, 1H64. Type Peniremtes stelliformis, Owen and 

 Shiimard. Three American species are referred to this genus, all contiued 

 to rocks of the Carboniferous period — Codonites campanitlaiiis, Hambach, C. 

 gracilis, M. & W., and the type species. The genus occurs in rocks of the 

 same age iu England, Ireland and Belgium. 



Order Irregulares, E. & C, 188G. 



This order has been established to contain three very remarkable genera: 

 Eleutherocriiuis omiinmurd &. Yandell, two species of which occur in the 

 Devonian rocks of America, and the British genera Astrocrinites and Pente- 

 phyllum. 



Astrocrinitidw, T. & T. Austin, 1813 (Emend. E. & C). This family is divided 

 into two groups. Tlie first contains Eleutherocrinas and Astrocrinites, T. &, 

 T. Austin ; the second FcnfephyUam, Haughton.

Review and abstract of. 



"The description of the various species of Blastoids is very limited both in 

 space and time. A few species appear to be common to the Upper and 

 Lower Devonian of A-narica, buteach oFthe great divisio:is of the Sub-car- 

 boniferous in the Mississippi Valley seems to have its own particular types. 

 No Blastoid occurs on both sides of the Atlantic ; one species is common to 

 the Devonian of Spain and Germany, and another to the Carboniferous 

 limestone of Britain and Belgium. But, with these exceptions, the range 

 of individual specific types is very limited indeed."
