Art. XXIX. — Notes on the Anatomy and Embryology of Scymnus lichia. 

 By T. Jeffery Parker, B.Sc. 

 [Bead before the Otago Institute, 15th August, 1882.] 

 Plates XXXI. and XXXII. 

 The shark Scymnus lichia is stated by Griinther* 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 [Lepiclojnis caudatus), the John Dory (Zeus faber), and several 

 other well-known fishes. 



As Scymnus has not previously been included in the New Zealand fauna, 

 I will quote Br. Giinther's diagnosis of the family and genus.
