. The Canadian field-naturalist. 1999 Notes 515. Figure 2. Close-up of head of False Catshark, Pseudotriakis micwdoiu NSM12550, south- east of Sable Island, Nova Scotia. The body is a slate-grey colour with no evident markings. Literature reports state that the body is dark brown in some specimens. Fins are generally darker than the body although in this specimen the first dorsal fin is lighter. Maximum size in the litera- ture is m total length for females and m for males. The description agrees well with those in Bigelow and Schroeder (1948), Compagno (1984, 1988), and Yano and Musi
. The Canadian field-naturalist. 1999 Notes 515. Figure 2. Close-up of head of False Catshark, Pseudotriakis micwdoiu NSM12550, south- east of Sable Island, Nova Scotia.

Fins are generally darker than the body although in this specimen the first dorsal fin is lighter. Maximum size in the litera- ture is m total length for females and m for males. The description agrees well with those in Bigelow and Schroeder (1948), Compagno (1984, 1988), and Yano and Musick (1992). The catshark was caught with 3178 kg of Atlantic Halibut, Hippoglossus hippoglossus, and a small number of Spiny Dogfish, Squalus acanthias. The False Catshark had been gutted and dressed at cap- ture and then weighed kg. The stomach is reported as containing nothing recognisable, just a "jelly-like liquid". Food is reported elsewhere to be predominately benthic bony fishes but also sharks, scavenged moribund or dead fish, squids and octopi, along with garbage from human activities (Yano and Musick 1992). It is an oophagous species, the embryos feeding while in the uterus on yolk material contained in ova produced by the ovaries (Yano 1992). Litter size is two as a result, one young in each uterus. This species is known world-wide from the deep waters of continental shelves between 200 and 1500 m including the western North Atlantic with one washed ashore at Amagansett, Long Island, New York, on 3 February 1883 (USNM 32516) and prob- ably one from a pound net at Manasquam, New Jersey, in July 1936 (Bigelow and Schroeder 1948). Shallow water records may be abnormal (Compagno 1984). The specimen described here is the first recorded from Canadian waters and only the third from the western North Atlantic.
