the five rays of the ventrals, and the white irides all better suit the com- 

 mon Pterophryne than any other Antennariid. 



In 1754, in bis Catalogue of the Museum of King Adolphus Fred- 

 erick,* Linnaeus again described, under the name "Lophius tumidus", evi- 

 dently the same species, as follows : — 

 li tumidus. LOPHIUS pinnis dorsalibus tribus. 



Balistes quae Guaperua chinensis. It. W. goth. 137. t. 3. f. 5. 

 Guaperua, Marcgr. bras. 150. Will. icht. 50. t. E. 2. f. 2. 

 Habitat in Pelago inter Fucos natantes. 



Corpus molle instar Ranae, adspersum ramentis cutaceis. Apertura 

 branchiarum ad axillas brachiorum s. pone pinnas pectorales, qua3 de- 

 currit ad pulmones ; alia apertura nulla, quod indicat affinitatem cum 

 Kauis. Pinnae in dorso tres: prima radio uno capiti insidet; altera pec- 

 tori radio uno instructa; tertia dorso radiorum duodecim, quorum duo 

 vel tres bifidi. Pectorales radiis 10, quae ulnis s. brachiis instruetae. 

 Ventrales radiis 5, hae ante pectorales basi ad pectus connexae. Ani 

 radiis 7 bifidis. Caudae radiis 10 bifidis." 



The soft body like that of a frog (and therefore naked and not rough) 

 and the cutaneous filaments are additional characters which corroborate 

 those given in the former work, and certify the relevancy of the descrip- 

 tions to the common Pterophryne. The habitat is also not the least im- 

 portant element in the determination of the Linnaean species, inasmuch 

 as the true Antennarii, so far as known, frequent chiefly coral groves, 

 while the Pterophryne is a pelagic species, principally affecting the 

 floating sea-weeds. There can then be no reasonable doubt that the 

 Antennariid of Linnaeus was the common Pterophryne. 



In 1758, in the tenth edition of the " Systema Naturae '\ Linnaeus first 

 introduced, and in 17GG, in the twelfth edition, retained, the name 

 " Lophius histrio", and in the synonymy of the species included refer- 

 ences to the two works just cited. The entire passage relative to the 

 species is as follows, in the twelfth edition (p. 403): — 



"histrio. 3. L. compressus.
