ii/iis (>]■ (•'t/roceras." In reference to these Mr. Billings remarks that 

 " althi.iiigh we have none of the characteristic spirifei's, cdi-als or trilobites 

 to guide us, yet I think that upon the evidence of the above fossils we 

 can safely say that this hica.lity is De\-iinian and most probably aljout the 

 age of the Hamilton group." The fossils from Manitoba Island, he adds, 

 "are jiiOhtly the same as those from 8nake Island, with the exception of 

 two speries of Cliimi'tea and fragments of a large tish. There is also here 

 a large Stfiiiii<itoi>or(i, proljably S. ruiimi/rini." 



The present wiiter has never seen the specimens referred toby Mi-. Bil- 

 lings as "two small species of Proihirtiis," and as " twcj species of Eiioiii- 

 'jilialits ' ; Ijut, apart from these, the following is submitted as an amended 

 list of tlic species obtained hy Prof. Hind at Snake Island : Oiihin utri-

 Prof. Hind at Manitolxx Island, and seventeen precisely simil.-ir ones 

 obtained by Mr. Tyrrell and the present writer at the same locality in 

 188,S, are all clearly referable to a single spi/cies, which is described and

 suies of I)evonian limestoiie examined by Prof. Hind are those at Flat 

 Bock Point, 8teep Bock Point and Ma,nitolia Island, on or in Lake Mani- 

 toba, and at 8nake Island, in Lake Winnipegosis. 



In 1S74 I*r. J. W. Spencer examined several outcroiis of ]>c\onian 

 rocks on the sh(jres of Swan L:ike, Manito))a, and Lake Wiinnj)egosis, and 

 ga\(' the name of Hawson I'.ay to the north-western jiortion of the latter, 

 in honour of Sii J. W. Dawson, the principal of McGill Ilidversity. 

 About a jKige and .t half (i)p. GI-Cil!) of Dr. S]iencer's Beyiort is dc\'oted 

 to a general description of Lakes Winnipegosis and Manitoba, and two 

 jiages (pp. ()7-tiS) to an account of the " 1 )e|iosil,s of I>cvonian Age in 

 and ar(jund Lake Winnipegosis an<l Swair Lake. On Jiage (iS he states 

 that "the best localities for fossils, so far as my obser\atioii extended, are 

 Warren Island, in Swan Lake, and Points Wilkins and Carrollida, on 

 Dawson Bay. The pakeozoic fossils whieh 1 collected have bei^i deter-
