Art. XXVI. — Description of a new Species of iEolis. By T. W. Kirk, 

 Assistant in the Colonial Museum. 

 [Read before the Wellington Philosophical Society, 9th December, 1882.] 

 The beautiful little animal described below was collected at Napier by Mr. 

 A. Hamilton, of Petane. Mr. Hamilton kindly forwarded specimens both 

 in glycerine and spirit, so that the bright colourings are to a large extent 

 preserved. I am also indebted to him for notes of colours, etc., taken from 

 living specimens. The accompanying figures of the animal are natural size. 



iEolis, Cuv. 



Animal ovate ; dorsal tentacles smooth, oval, slender ; papillae simple, 

 cylindrical, numerous, depressed, and imbricated ; mouth with a horny 

 upper jaw, consisting of two lateral plates united above by a ligament ; 

 foot narrow ; tongue with a single series of curved, pectinated teeth ; 

 spawn of numerous waved coils. 



Molis gracilis, sp. nov. 



Body small ; tail sharply pointed. Gills as long as greatest width of 

 the body, papillose, crowded, but placed in three tolerably distinct groups 

 on each side of a broad clear line running from the base of the tentacles 

 to the tip of the tail ; oral tentacles subulate, rather distant, about twice 

 as long as the greatest width of the animal. Tentacles approximate, about 

 half as long as the oral tentacles. Foot expanded, produced in front, 

 margin thin, slightly puckered. 



Colour — body and foot pale pink ; tentacles and gills bright red pro- 

 minently tipped with white. 



Length, *9 of an inch. 



Hab. — On Viva, Napier (collected by Mr. A. Hamilton).
