4. Remora jacobaea = (E. remora, Gthr.) = E. postica, P. (105 mill.) 



5. Remora osteochir = (E. tetrapturorum) (200 mill.) 



We may await the publication of the second edition of the " Conspectus 

 Piscium Cubensium," before accepting the preceding identifications as cor- 

 rect ; in that publication, M. Poey, influenced as usual by his desire for truth, 

 will correct the nomenclature of his species, and have no hesitation in re- 

 uniting some of tbem if a future examination should lead him to doubt the 

 correctness of his former views. I shall only remark that, among the species 

 of the group of Echeneides, there is a definite ratio in the form of the caudal 

 to the size of the species, and that the difference of dentition has been ex- 

 aggerated. After an examination of many specimens from the most distant 

 seas, I have also been, like Grunther and Richardson, unable to discover any 

 differences which could be regarded as specific. The habits of the representa- 

 tives of this family would indeed render it not improbable that they should 

 be very widely distributed. 



The genus Nomeus of Cuvier probably belongs to a peculiar family (Gas- 

 teros chismatoidae.) Lampris likewise represents a special family (Lainpri- 

 doidae.) 



With Dr. Bleeker, I am now disposed to believe that Aulostoma, Lac. and 

 Solenostomus, Gron. belong to different families, but, contrary to his opinion, 

 think that they are very nearly related. 



The Malacanthini of Poey form a natural family. The Latilus chrysops, Val. 

 does not, however, appear to be congeneric with the type of Latilus, but is 

 distingushed by its form and the structure of the fins. It may be called Cau- 

 lolatilus chrysops. 



The Labroidae are represented by six genera, Lachnolcemus, Cuv. Harpe, 

 Lac. (= Cossyphus, Cuv.), Decodon, Gthr. (Cossyphus puellaris, Poey) (= La- 

 brinae), Choerojulis, Gill (Halichares, Riippell), (= Julides), Xirichthys, 

 Cuv. (= Xirichthyinse), and Clepticus, Cuv. (= Clepticinae). In retaining 

 the Labroids at the end of the symmetrical physoclystous Teleocephali in the 

 Catalogue of the Fishes of the Eastern Coast, it was by no means intended 

 to convey the ideas of the author as to the affinities of that family. Its 

 affinities have indeed expressly been said (p. 7) to be "probably rather with 

 the Scisenoids, the Cha?todontoids and even the Percoids," &c. As, however, 

 they were not quite evident, the Pharygognathi were provisionally retained 

 where Miiller had placed them. The families are nearly related to each other 

 and should not be scattered. The most appropriate position is probably near 

 the Centrachoids. 



The single Cuban species of Polynematoid belongs to the genus Trichidion 

 of Klein, as recently restored. 



The Gobioids are represented by four subfamilies and ten genera. 



The Gobiinae with four genera, Gobiu&, Art. (mapo, P., lacerlus, P.) ; Lo- 

 phogobius, Gill (crista-galli), characterized especially by a longitudinal coro- 

 nal crest; Gobionellus, Grd. (= iSamaragdus, Poey) ; Awaous, Val. (= Rhino- 

 gobius, Gill = Chonophorus, P.) Eleotridinae with three genera, Eleotris, 

 Gron. (gyrinus, guavina) ; Dormitator, Gill (Gundlachi, P., omocyaneus, P.), 

 readily distinguished by the form, the cleft or extension forwards of the 

 branchial apertures above the operculum and the large scales ; Pkilypnus, Val. 

 and Erotelis, Poey, 



Ainblyopodinae with the genus Gobioides, Lac. 



Sicydiinae with the genus Sicydium, Val. 



The Eleotridinse cannot be separated from the Gobiinae, as the physiognomy 

 is not only similar, but there is almost a transition from one form to the other. 



The Cyclopteroids are certainly not natural associates of the Gobicsocoids, 

 the latter forming a very distinct family. Prof. Poey has committed the same 

 error as Dr. Girard in describing the ventral fins as lower pectoral rays, and
