(Belaque, the native name of the alUed U. sulphureus at San 

 Fabian, P. I.) 



Argyrosomus goldmani (Bleeker). 



Small example and two adults wliich agree with Bleeker's figure, 

 especially in length of second anal spine. My examples show latter 

 2| in head, and jaws about even when closed. 



Sciaena dussumieri (Valenciennes). 



Several examples. Contrary to the contention by Jordan and 

 Thompson-^ that the "substitution of Scicena for JJnibrina by Bleeker 

 is not warranted bv the rules of the International Zoological Con- 

 gress" in my opinion the type of a genus must be a species originally 

 included in the genus under its distinct original binomial. As Gill 

 designated S. aquila Cuvier the type of Scicena Cuvier-^ which 

 evidently was the Cheilodipterus aquila previously described by 

 Lacepede and therefore definitely indicated a species not recognized 

 by Linnaeus or named in his original account, Gill's action is invalid. 

 The first actual designation of Scicena cirrhosa Linnaeus as the type 

 of Scicena Linnaeus, by Bleeker,^" correctly argues that Scicena 

 supersede Umhrina, and the designation of Scicena umbra by Jordan 

 and others^^ is invalid. 



Polydactylus plebius (Broussonet). 



Three examples. Jordan and Evermann are wrong^- in attempting 

 to fix Polynemus paradiseus Linnseus as the type of Polynemus 

 Linnaeus, as Gill designates Polynemus quinquarius Linnaeus^^ many 

 years before 1883. Polydactylus will therefore remain the correct 

 generic name for the present species. 



Pomacentrus violescens Bleeker. 



Four examples, which agree in the squamation and general colora- 

 tion as shown by Bleeker. He gives the pectorals as clear violaceus 

 with their bases commonly with a spot or transverse blackish or 

 dusky streak. P. philippinus Evermann and Scale is very closely 

 allied, if not identical. It is figured with 3 rows of scales on the 

 cheek, the lowest on the preopercle limb. Its teeth are said to be 

 small and uniserial.
