snout to tlie nape. The first and last rays arc usually j-qual in loii^tli, 

 and <'qual the length of the snout. The longest anal ray equals in length 

 the caudal i)cduuclc. 



The length ul" the middle caudal rays is contjiintd liuni 5 to G times in 

 the unit of length. 



The distance of the pectoral from the snout is contained 3J times, and 

 its length 3;^ to 4 times in the unit of length. 



The distance of the veutral liom the snout equals twice the length of 

 the upper jaw. The length of the ventral in females is contained o 

 times (in one nearly 6 times) in the unit of length; in males, about 4.\ 

 times.

Dr. Liitken is of the opinion that '■'' Cottus pachypus Giinther (from 

 Port Leopold) is the genuine C. scorpioides^^^ in which opinion I fidly 

 coincide afteu a comparison of ]Mr. Kumlien's specimens with Fabricius's 

 description of C. scorpioides and the description of C. pachupiis. 



Cottus HcorploidcH appears in Professor Gill's List of East Coast Fishes 

 with a doubt as to its reference to the genus Cottun, to which genus, 

 however, it was properly referred by Fabricius.
