The following is tlie original diagnosis of Cnrapus (Raf., Indice d'lttiol. 

 Siciliana, 1810,57): 



"XII. Gen. Carapus. Kessnn' ala dorsale, ne caudale, un' ale anale, e 

 due ale pettorali, mascella superiore piii luuga dell' iuferiore, coda nuda 

 al disotto. Osserv. Dift'erisce dal vero genere Gymnotus, che ba 1' ala 

 anale lunghissima, ricuoprendo 11 disotto della coda, e la mascella iu- 

 feriore pill lunga della superiore." 



IS'o species is here mentioned, but in the list of Sicilian fisbes, on page 

 37, we find : 



"272. Carapus acus. Raf., App. gen. 12 (Gymnotus acus Linn.) Ca- 

 rapo aguglia. Anciduzza." 



We find tbat tbese two genera correspond to tbe first and second sub- 

 genera recognized under Gymnotiis by La Cepede, the first (" Gymnotus'''') 

 \VLQ\\i(\.mg electricus, putaol {fasciatus), and alhus; the second (" Carapus''^) 

 including carapo^ Jierasfer {=acus L.), and longiro stratus. Tbe name Ca- 

 rapus is evidently suggested by " Carapo^^'' and the generic diagnosis 

 of Rafinesque above quoted seems to be entirely extracted from Gmelin's 

 il(i'iiQ.T:{\)i\o\\ oi Gymiiotus carapo ['■^ Gymnotus * * * dorso apterygio, 

 pinna ani longitudine, * * * maxilla superiore lougiore * * * 

 ani piuuiie in caudie apicem non excurrens, sed ante caudse pinnam 

 desinens"). The diagnosis does not apply to the species ofFierasfer, 

 wliich have a distinct dorsal fin. It seems, therefore, proper to consider 

 Gymnotus carapo L. the type of Carapus Raf., while G. electricus L. is 

 evidently the type of Rafinesque's Gymnotus. 



In the tenth edition of the Systema Nature, but two species are 

 referred to Gymnotiis, G. carapo and G. asiaticus, the latter not being 

 a member of this group. If we date our nomenclature from this tenth 

 edition, G. carapo L. must be taken as the type of Gymnotus, Carapus 

 Raf. being a synonym of Gymnotus, while the name Electrophorus Gill 

 should be used instead of Gymnotus for Gymnotus electricus L. (ed. xii). 



89. Citharichthys spilopterus Giiutlier. 



90. Antennarius sanguineus Gill. 



91. Antennarius strigatus Gill. 



An adult example, 10 inches long, agrees in but few respects with 

 the descriptions drawn, by Gill and Giinther {Antennarius tenuifilis), 

 from immature examples. 



First dorsal spine elongate, filiform, twice the length of the second, 

 with very slender dermal tip. Third spine more robust than second, 

 wholly concealed in the skin, its length equal to that of first spine. 

 Lips, maxillary, and a large transverse area behind second dorsal sjnne 

 naked, each side of this area with a few sjiinous tubercles. Skin else- 

 where covered with fine shagreen-like armature.
