For " Campopiiyllum ellipticum " read: 



Cyatiiophyllum McConnf.lli. (N. Sp.) 



The reference of the three corals from the Hay Ptiver, mentioned on p. 

 202, to th(; Choiiophylluni ( J'tychopliyllvni) elliplicinii of Hall and Whit- 

 field, under the name CampopJiyUuin- ellijiiir.um, has not proved satisfactory. 

 Profes'^or Calvin, who has recently cumpared the best of them, the original 

 of Plate 27, fig. 5, of this vdlume, with Towa specimrns, thinks that it is 

 generically but not speeitically identical with Hall and Whitfield's spe- 

 cies. Rominger, also, in his J'^ossil Corals of .Michigan, page 104, says 

 that C. elli.])t/ic'iivi is not a Climuipliyll'inii. but a CyatltujiJiylhmi allied to 

 C. llduylilirai. Under these circumstances it i-ecms most prudent to di.s- 

 tinguish the three Hay River sp' cimcns tVirmerly designated as (Jampo- 

 phylhim. I'llijiticii.in b}' the foregoing new specific name, in honour of their 

 discoverer, and to refer them provisionally to the genus ('yathoj>hylhi,in.

The corals from the Peace and Hay rivers which were referred to this 

 species, were so identified solely by their external characters. Sections 

 since made shew that they and the spe; imens from the Hay River re- 

 ferred to J'Jiillipi^iisl.rii^a Verrillii, have more the structure of I'nchypliylliini 

 than of P]dlli]tsii.sl rii'd. proper, though Rominger maintains (Fossil Corals 

 of Michigan, page 127) that the separation of these two genera is both 

 " ai'tificial and inappropriate.'' It is (juite likely that all those which have 

 been identified with I'liillipsaxlrwa llennald are mere varieties of Pachy- 

 phyUmn Woodiiiani, although the specimens from the Hay River have 

 rather smaller and less prominently exserted calyce.-, with a somewhat 

 smaller number of septa.
