same naturalists at Port Jackson resembles the Port Arthur fish in the 

 form of the dorsal spine and shape of the three vertical fins, but the 

 numbers of the rays in the dorsal and anal are different ; there are 

 no spots on the body, and merely a single dark line extending from 

 the angle of the mouth along the higher part of the sides. In both 

 the Port Arthur Aleuteres the minute prickles of the skin, when ex- 

 amined by a good microscope, appear to be solitary, and to spring 

 from a globular base. 



Callorh-xnchus Tasmanius (Nob.). Tasmanian Cullorhynchus. 

 Call., pinnis pectoralibus ad ventrales hand attingentibus ; p'mnd 

 dorsi secundd pone ventrales incipienti, ante lobum anteriorem in- 

 feriorem piniia cauda desinenti. 



This species agrees with the Callorhynchus Smtjthi of Bennet, 

 figured in Beechey's Zoological Appendix, in the distance between 

 the pectorals and ventrals, but is so unlike that figure in other re- 

 spects that it is im])ossible to assign it to that species. Call. An- 

 tarcticus has large pectorals whose tips overlie the base of the 

 ventrals. 



Narcine Tasmaniensis, {'Hohj). -Tasmanian Narcine. 



This species has not yet bdeh compared with Narcine capensis, 

 but it is most probably distinct. A full description is given in the 

 paper, to enable authors who have the ojiportunity of seeing figures 

 or recent specimens of Narcine capensis, to point out the differences. 

 It is named " Ground Shark" at Port Arthur and HobartTown. 



Syngxathxis ARGUS (Nob.). Ocellated Pipe-Fish. Syng., depressus, 

 latns, pinnis pectoralibus dorsique praditus ; ventralibus caudceqiie 

 orbatis ; dorso macuUs oculeis ornato ; maculis albis und serie in 

 margine ventris dispositis. 



This very handsome pipe-fish differs from all the groups of species 

 indicated in the Regne Animal, in having pectoral fins, while the 

 ' caudal and ventrals are wanting. It did not form part of Mr. Lem- 

 pri^re's collection, but is said to have been presented to the Haslar 

 Museum by the surgeon of a convict ship ; its exact habitat being 

 unknown. 



It was mentioned in the former paper that labels of many of the 

 specimens were detached, so that correct references could not be 

 made to Mr. Lempriere's list. In this predicament is the ' Saw-fish" 

 or ' Bugler,' which attains the weight of sixteen pounds, but the 

 example sent was below the usual size. Also one of the ' Parrot 

 Fish,' known locally as the ' Blue-head.' The Thyrsites altivelis is 

 named the ' Baracoota,' and Mr. Lempriere says that there is a se- 

 cond species taken at Port Arthur, which has much lower dorsal 

 spines, but is more esteemed as an article of diet. This is probably 

 the Thyrsites utiin of the Histoire des Poissons. The most choice 

 fish in the colony is called the ' Trumpeter', and weighs, when full- 

 sized, eight or nine pounds. A single specimen of this was sent, 

 and is doubtless described in this or the former part of the paper.
