they split unevenly with a jagged fracture, and have also a tendency 

 to divide up into cuboidal fragments. 



The material which has now been placed in my hands may be 

 summarized thus : — 



No. 1. One specimen of a dark nodule, split into halves 

 (3" X If ')j exposing the cephalothorax and portions of the limbs of 

 a Crustacean referred to Linupdrus (Podorrates) Vancouverensis by 

 Whiteaves (PI. XV, Fig. 1), described in Trans. Eoy. Soc. Canada, 

 ser. II, vol. i (1895-6), sect. 4, pp. 132 and 133. Formation : from 

 the Nanaimo Group (Upper Cretaceous), Museum Geol. Surv. Canada. 

 Locality : from two miles up the Pimtledge (called also the Comox) 

 Eiver, Vancouver Island ; collected by the Rev. G. W. Taylor, 1889. 



No. 3 (labelled also 58 in white paint). A large dark nodule, 

 split in halves (6|" X 3f"), exposing the dorsal aspect of a second 

 specimen of Linupdrus (P.) Vaiicouverensis, W., showing the cephalo- 

 thorax and a portion of the base of the left antenna. The three 

 characteristic longitudinal ridges, the small central pear-shaped 

 area in front of the neck-furrow on the carapace, and five of the 

 abdominal segments can also be seen (Trans. Roy. Soc. Canada, 

 op. cit.). Formation: Upper Cretaceous. Locality: Hornby Island ; 

 coll. by W. Harvey, 1893. 



No. 4. A long, dark, and rather cylindrical noclule (6^" X 2^")> 

 split in halves and also broken aci'oss transversely, exposing the 

 interior of the cephalothorax and five segments of the abdomen of 

 Linupdrus (P.) Vancouverensis, W. (PI. XV, Fig. 3). The upper 

 surface of the carapace is not preserved, but the bases of the 

 mandibles (m.) are exposed, the monodactylons walking-legs, and 

 the bases of the antennules. The epimeral portions of the abdominal 

 segments are serrated behind, and bear small tubercles on the 

 surface. Formation : Upper Cretaceous. Locality : Comox River, 

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



No. 6. Half of a nodule only (7" X 4f"), containing an obscurely 

 preserved Crustacean, Liniqjdrus (P.) Vancouverensis, showing 

 characteristic traces of the carapace and limbs and the nearly entire 

 abdomen, including 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 b. Two sides of a dark egg-shaped nodule split 

 open (4|" X 3|"), exposing the dorsal aspect of a specimen of 

 Linupdrus {P.) Vancouverensis, W. (PI. XV, Fig. 2), 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. Robbins in 1896, Provincial 

 Museum, Victoria, British Columbia. 



A few additional specimens from the same series are referred to 

 later on.
