A single specimen of this fish in the collection, agrees in most par- 

 ticulars with tlie description of Thyrsites aiien in the Histoire des 

 Foissons, but the spinous rays of the dorsal fin are considerably higher 

 in proportion, and the teeth on the jaws much fewer. 



12. Blennius Tasmanius is an undescribed species strongly re- 

 sembling some of the European ones. 



13. Clinus despicillatus differs from C . perspicillatus of the His- 

 toire des Poissons in possessing a thicker form, a larger head, a pro- 

 portionably smaller eye, and in wanting the nuchal marks which 

 give the name to that species. The marks on the body are arranged 

 as in perspicillatus, but there are three transverse bands on the pec- 

 toral and caudal fins, with many other spots not mentioned in the 

 description of the latter. The dorsal rays are 36, 4, and in other 

 particulars the two fish seem to be much alike.

 ralibiis puniceis purpurea niurginatis, postice in unum coalesccn-

This is a very handsome species, having a duck-green colour, with 

 two lake-red stripes, commencing at the gill-opening and uniting 

 opposite the end of the dorsal to form a single broader stripe wliich 

 is continued into the caudal fin. Tliese stripes are bordered on both 

 sides by dotted lines of plum-blue, and there are also five rows of blue 

 spots on the sides of the belly, and three rows near the base of the
