Art, XXIX.—wNotes on the Anatomy and Embryology of pee: lichia. 
By T. Jerrery Parker, B.Sc. 
[Read before the Otago Institute, 15th August, 1882.) 
Plates XXXI. and XXXII. 
Tue shark Scymnus lichia is stated by Günther* to be confined to the Medi- 
terranean and neighbouring parts of the Atlantic: its range must now, 
however, be extended to include the South Pacific, since the specimen from 
which the following notes were made was caught off Pilot Beach, near the 
Otago Heads, by Coxswain Milne, who immediately sent it, fresh and 
uninjured, to the museum. It would be of great advantage to zoology if 
Mr. Milne’s example were followed by others enjoying similar opportunities. 
Scymnus lichia must, therefore, be added to the list of marine fishes in- 
habiting both the Northern and the Southern Oceans, a list which includes 
the porbeagle (Lamna cornubica), the piked dog-fish (Acanthias vulgaris), the 
frost-fish (Lepidopus caudatus), the John Dory (Zeus faber), and several 
other well-known fishes. 
As Seymnus has not previously been included in the New Zealand fauna, 
I will quote Dr. Giinther’s diagnosis of the family and genus.
