228 FAUNA OF NEW ZEALAND. 



Fam. CYCLOSTOMI. 



92. Heptatrema dombe yii. Lacepede, Cuv. Reg. An. 2, 

 p. 405. (Petromyzon cirrhatus, G. Forster, fig. 

 pict. 2, t. 251, Bl. Schn. 532.) 

 Inhabits Dusky Bay. 



The preceding list is extracted from a Report on the Ichthyology 

 of New Zealand, read at the Manchester Meeting of the British 

 Association, and which will appear in the annual volume of that 

 Body. To this has been added the description of the new species 

 brought home by Dr. Dieffenbach. 



IV. CATALOGUE of the SPECIES of MOLLUSCA and their 

 Shells, which have hitherto been recorded as found at NEW 

 ZEALAND, with the Description of some lately discovered 

 Species, by J. E. GRAY, F.R.S., &c. 



Like the shells found in the other parts of the southern 

 ocean, many of them are of a larger size and brighter 

 colour than the species found in the same latitude in the seas 

 of the northern hemisphere, and this is particularly the case 

 with the terrestrial groups; some of them belong to genera 

 which are only found in the warmer part of the northern 

 half of the world. The genus Struthiolaria is peculiar to New 

 Zealand. It is probable that some of the species which are 

 inserted in this list, on the authority of Favanne, Chemnitz, 

 and other of the older authors, may be found to have 

 been placed in it erroneously ; for before attention was paid 

 to the geographical distribution of animals, persons were 

 not so attentive to the particular habitats of the species, and 

 many of these shells must have passed through several 

 dealers' hands before they reached their describers. I have 

 marked the more doubtful with an asterisk.
