istics, debility, as exemplified in ornamentation of different 

 parts of the organism Gaspelichas Forillonia, a new species, is 

 indeed "the most extravagant instance of the development of 

 spines among the trilobites." 



This monumental work by Dr. Clark only serves to enhance 

 his deserved fame as a distinguished palaeozoic palseontologist. 

 The plates are all that can be desired, the text likewise so satis- 

 factory, both as to quality and precision. References are made 

 to the good w^ork done in the peninsula by Logan, Billings, Ells, 

 Low and others whom the author does not forget in bestowing 

 names on the new formis met with. Nor does he forget those 

 intrepid missionaries and early French explorers like Lejeune,' 

 Jvimeau, Lescarbot, Leclercq and de Thune. and the Jersevmen 

 and other settlers of the district, all who have in anv measure 

 contributed to the history and development of Gaspe. 



The geology of the "Forillon" with map, is given in which 

 the Gaspe sandstones, the Grande Greve limestones, the Cape 

 Bon Ami beds and the St. Alban beds are separated on palfeon- 

 tological and stratigraphical grounds. This remarkable point 

 juts out into the Gulf of St. Lawrence "like an index finger," 

 from the broad fist of Rosier Cape and Cove, and two of the four 

 geological formations constitute the narrower portion of the 

 slender point, with Cape Gaspe to the north and Shiphead to the 

 south. The vertical distribution of species, the faunas of the 

 different formations and their mode of occurrence, together with 

 a special chapter on the "Geology of Perce." in which a geological 

 map in detail, is presented giving the succession of the strata, 

 including formations from the Carboniferous down to the 

 Lower Silurian. They comprise the Bona venture conglomerate 

 (Carboniferous and Devonian in age), the "Perce massive" 

 (Lower Devonian), the Cap Barre massive, (Lowest Devonian), 

 Mt. Joli massive, north flank, (Upper Silurian). Mt. Joli massive, 

 south flank, (Lower Silurian). Cape Canon massive, including 

 limekiln beds, (Lower Silurian). The faults noted bv Dr. Clarke 

 appear to be of the some character as those of the "Quebec 

 Group" and "Appalachian" folded region, a series of thrust 

 faults, very much like those movements so characteristicallv 

 described by Lugeon of Swit?:erland , where strata seem to plav 

 leap-frog one over the other. Their reproduction of a number of 

 old historic maps and early illustrations of this most interesting 

 and picturesque, as well as easily reached region, forms no in- 

 conspicuous portion of the volume, nor can the delightful water- 

 colour reproduction of Perce rock, forming the frontispiece, go 

 unnoticed. The excellent drawings by Barkentin illustKvting 

 the extinct faunas are exquisitely reproduced. y^^^^^Al
