"No. 4. A long, dark, and rather cylindrical nodule (6J'' x 2V'), split 

 in halves and also broken across transversely, exposing the interior of 

 the cephalothorax and five segments of the abdomen of Linupat-us (P.) 

 Vancouverensis,W ." (PI. 40, Fig. 2). " The upper surface of the carapace 

 is not preserved, but the bases of the mandibles (m.) are exposed, the 

 monodactylous walking legs, and the bases of the antennules. The epi. 

 meral portions of the abdominal segments are serrated behind, and bear 

 small tubercles on the surface. Formation: Upper Cretaceous. Locality: 

 Comox Eiver, Vancouver Island ; coll. by J. B. Bennett, 1895. 



"No. 6. Half of a nodule only (7' x 4|"), containing an obscurely pre- 

 served Crustacean, Linuparus ( P . ) F^cincoiruere/isis, showing characteristic 

 traces of the carapace and limbs and the nearly entire abdomen, inclu- 

 ding remains of the caudal appendages. The posterior borders of the 

 epimera are spinous. The right antenna is preserved for a length of 2^ 

 inches. Formation : Upper Cretaceous. Locality : Hornby Island ; 

 coll. by W. Harvey, 1895. (Specimen also marked No. 1 in ink.) 



" No. 55 a and h. Two sides of a dark egg-shaped nodule split open 

 (4|^" X 3|"), exposing the dorsal aspect of a specimen of Linuparus (P.) 

 Vancouver ensi^. W." (Pi. 40, Fig. 3), " showing the carapace and the five 

 abdominal segments, also the remains of the caudal appendages and the 

 thoracic limbs. The three characteristic ridges are well seen, also the 

 cervical furrow, with its pear-shaped tuberculated area just in front. 

 Formation : Upper Cretaceous. Locality : Hornby Island ; coll. by Mr. 

 Bobbins in 1896, Provincial Museum, Victoria, British Columbia."

The type of this species is a single specimen from the Cretaceous shales 

 of the Highwood Biver, Alberta, collected by Mr. R. G. McConnell in 

 1882. The Highwood is a tributary of the Bow River, and the shales at 

 that locality are supposed to be the Canadian equivalents of the Fort 

 Benton group of the Upper Missouri section.
