140 Third Annual Report of tlie 



grammiste, to which he has given provisionally the name of 

 Grammiste comprinie, and the Report takes the opportunity of 

 pointing out a typographical error in the work of Cuvier and 

 Valenciennes on Fishes, vol. ii. p. 206, which alters the locality 

 assigned to the Grammiste Oriental, remarking that for Neros 

 in that work we should probably read Peros Banhos, this 

 latter name being applied to a shoal and small island of the 

 Archipelago of Diego Chagas, situate about 400 leagues N. E. 

 of the Mauritius, and on which several persons from the 

 Mauritius have established fisheries. The name in Portuguese 

 signifies the shoal of dogs ; so called, in all probability, from 

 the great abundance of sea dogs in that Archipelago. The 

 Report then notices the Cirrhite d bouche cloisonnee, discovered 

 by Mr. Lienard, which is remarkable for a membrane attached 

 to the Palate, and forming a sort of vertical operculum in the 

 cavity of the mouth. It then remarks that Icthyologists have 

 long given notice of a fish having power to extend an elongated 

 retractile snout, and to eject by this means a quantity of water 

 upon those insects which it wished to capture. It is the /?/o«, 

 the Sparus insidiator of Lin. Gmel., figured by Bonaterre in the 

 Encyclopedie Methodique, in a rude but characteristic manner. 

 Authors notice India as its locality. Mr. Lienard, senior, has 

 however, been so fortunate as to procure a specimen at the 

 Mauritius, where it appears to live on the Crustacea and Poly - 

 piers. According to the report of the fishermen, it does not 

 frequent deep waters, but is generally found along the shoals, 

 as far as the depth of fifteen fathoms. 



Mr. Lienard also brought to notice the existence in those seas 

 of the Trichinrus Lepturus, (Linn.) The fishermen seemed 

 then to have remarked this fish for the first time, a considerable 

 shoal having found its way into the anchorage. 



Mr. Lienard also has remarked, in regard to the Genus 

 Zanclus ; that in all the species found round the Mauritius 

 there occurs only one filament beside the dorsal fin, instead 

 of two, as represented in plate 177, of Histoire Naturelle des 

 Poissons, Mr. Elysee Lienard communicated two descriptions 

 of species of Holocanthus, which do not occur in the Histoire 

 Naturelle des Poissotis, and which he is convinced are new. 



Mr. J. Lienard read a detailed description of a Labrus, which 

 ought to constitute a new sub-genus between the anampses 

 and the odax, 



Mr. Julien Desjardins described two new species of the 

 proper Chaetodons, to which he gave the names of Ch. Festivus 

 and Ch, Chrysuriis.
