The type of the present species belongs in the collection of the Geological Survey of Canada. 
It, together with at least one other specimen, was collected by Mr. [eaeeeonee M. Lambe, of the 
Survey, from beds belonging to the Belly River series, equivalent to the Judith River beds. The 
locality is the mouth of ‘Berry Creek, on the Red Deer River, Alberta. The type consists of 
the anterior half of the carapace and the complete plastron. The other specimen furnishes the 
anterior portion of the carapace only. Through the kindness of the discoverer of the species the 
writer has had the opportunity of examining it. 
Fic. 88.—Boremys pulchra. Carapace of type. 4. From Lambe’s figure. 
pren, preneural; sm, supramarginal scutes. 
The specimen was originally referred to Baéna hatcheri tor the reasons that it was not then 
generally accepted that the Judith River formation was distinct from the Laramie, that the 
specimen is somewhat crusht, that it resembles in various ways B. hatcheri; and for the reason 
finally that the presence of the supramarginals was then overlookt. The broader front of the 
carapace was noted and caused some hesitation. The presence of the supramarginals and 
the small preneural makes the separation of the species as the type of a new genus justifiable. 
The type specimen was a rather small individual, having close to three-fifths the length of 
the type of Baéna riparia and a little more than one-half that of B. hatcherz. The carapace 
(fig. 88) had a length of about 195 mm. It is doubtful whether the width has been increast 
by the crushing to which it was subjected. 
The front of the carapace is considerably broader and more rounded than that of B. 
hatcher1. The neurals, so far as preserved, appear to differ in no important respect. The 
first appears to be transversely divided into two parts. The anterior portion is to be regarded 
as a preneural, such as is seen in Chisternon. The shortness of the nuchal bone is remarkable. 
Whereas, in B. hatcher: and other specimens of Baéna which reveal the sutures, the nuchal has 
about the same fore-and-aft length as the first neural, in Boremys pulchra the nuchal is not 
one-half as long as the neural. Its width is about 4 times its length.
