average distance of two or three centimeters from it. At the 
region between the posterior dorsal and the caudal fins, where 
the dorso-ventral thickness of the fish is slight, the canal is some- 
what nearer the dorsal than the ventral body line. Just back 
of this point, however, the line drops rather suddenly to the lower 
edge of the body and extends to the end of the tail close to the 
union of the caudal fin with the body (fig. 1, Z')- 
According to Garman the course of the lateral canal in C. mon- 
strosa ('88) is practically the same as in C. colliei, while in Rhino- 
chimaera pacifica ('04) it is essentially the same, except for the 
absence of the upward bend near its anterior end. In Callo- 
rhynchus antarcticus Garman ('88) figures the lateral line about 
as it is in the ordinary sharks, without either the anterior up- 
ward bend or the posterior downward one. Garman neither
