the five rays of the \ eatrals, aud the white irides all better suit the com- 

 mon Pterophryne than any other Antennariid. 



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

 erick,* Linn sens again described, under the name '■'■Lo'pMns twnidiis^\ evi- 

 dently the same species, as follows : — 

 "tumidus. LOPHIUS pinnis dorsalibus tribus. 



Balistes quae Guaperuachinensis. 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 natautes. 



Corpus molle iustar Eanae, adspersum ramentis cutaceis. Apertura 

 branchiarum ad axillas brachiorum s. pone piunas pectorales, qusB de- 

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

 Ranis. 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 iustructce. 

 Ventrales radiis 5, hse ante iiectorales basi ad pectus connexte. Ani 

 radiis 7 bitidis. Caudae radiis 10 bifidis." 



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

 and the cutaneous filameuts 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 r.lso not the least im- 

 portant element in the determination of the Linnaeau species, inasmuch 

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

 while the Pterophryne is a pelagic species, i)rincipally affecting the 

 floating seaweeds. There can then be no reasonable doubt that the 

 Antennariid of Linuiieus was the common Pterophryne. 



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

 introduced, and in 1760, 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): —
