On pages 207 unA 26S another arrangement of tlie Synanchin?e or 

 '" Hogfish'' is given with quasi-detinitions and designation of t3"pes, viz: 



Agriopus. 



Pelor. 



Synanchia, witli thrt'e .suhjjeiitn'a, viz: 



Synanchia (erosa) 



Buflchthys (horrida). 



Trachicephalus (elongatus). 

 Trichodoii. 



The detinitions are, in a couph' of cases, practically exchanged with 

 those on former pages, so that the equivalents are as follows: 



p. 268. p. 61. Pp. im, 181. 



Synanchia. Erosa Bufichthys. 



BiifichthyH. Synanchia. Synanchia. 



Trachicephalus. Trichophasia. Trachicephalus.

The mutations being published at the same time, it may justly be 

 considered that we may have the right to accept the fullest expression 

 of opinion as the d(^termining one. Still more, the data on the pre- 

 vious pages are too meager and defective oth(»rwise to determine what 

 Swainson meant. It is only by comparison with the last exposition 

 that we are able to ascertain what was intended by his former schemes. 

 The preceding ones may ])e thus canceled, and the last is left to adopt 

 or otherwise, as the history of the nomenclature may indicate. 



In 1874 P. Bleeker pul)lished a " Revision des especes insulindiennes 

 de la famille des Synanceoides," in which he recog'nized four genera, 

 exclusive of one not occurring in the region under consideration. 

 The four corresponded essentially to the Swainson ian (pp. 267, 268), as 

 follows: 



Bleeker. Swainson. 



Pelor. Pelor. 



Synanceia. Bufichthys. 



Leptosymanceia. 



Polycanlus. Trachicephalus. 



The remaining genus was named Si/tKnirJuc after Swainson. and its 

 type was .S'. croxa. 



In 1904 Jordan and Starks admitted four genera, having had no 

 occasion to mention the others. The four may ])e thus correlated with 

 genera admitted by Bleeker. 



Jordan and Starks. Bleeker. 



Synanceia. Synanceia. 



Erosa. Synanchia.

The conclusions forced on the present writer agree essentially with 

 those reached by Jordan and Starks. As indicated by them, " Si//)-
