(Fig. 5, i.) Kaupichthys diodontus, new genus and species 



1&. Pectoral fins absent ; anus more than two head lengths behind gill openings. 

 2a. Origin of dorsal fin nearer to gill opinings than to anus, and al)Out half 

 the distance from tip of snout to anus ; head contained 1.8 to 2.0 times 

 in distance from tip of snout to origin of dorsal fin; snout pointed and 

 extending much beyond tip of lower jaw, the part beyond lower jaw 

 contained three times in snout. The following proportions were made 

 from measurements taken on 163 and 234 mm. specimens : Depth 36 to 

 46; head 9.3 to 9.8; tip of snout to anus 2.34 to 2.63; snout to origin 

 of dorsal 4.97 to 5.1; length of tail 1.61 to 1.65, all in total length. 

 Depth 3.C5 to 5.0 and month 3.3 to 3.55, both in head. Snout 1.6 to 1.72 

 in lengtli of gape of mouth. Eye 1.95 to 2.06 in the snout. Head 3.54 

 to 3.87 in distance from tip of snout to anus. (Fig. 5, /.) 



Muraenichthys macropterus Bleeker 



2b. Origin of dorsal fin much less than one head length in front of anus or its 



origin behind anus; head contained more than three times in distance 



from tip of snout to origin of dorsal fin. 



3a. Tip of snout pointed, flattened on ventral surface and projecting beyond 



tip of lower jaw as much as or more than diameter of eye; teeth 



on maxillary in two irregular rows, and on dentary two or three 



rows anteriorly becoming one posteriorly ; vomerine teeth miiserial. 



The following proportions were computed from measurements made 



on 81 and 104 mm. specimens : Depth 45 to 50 ; head 9.3 to 9.5 ; 



tip of snout to anus 2.27 to 2.3 ; snout to origin of dorsal 1.73 to 2.08 ; 



length of tail 1.76 to 1.78, all in total length. Depth 3.7 to 5.3; 



mouth 3.61 to 3.87, both in head. Snout 1.47 to 1.48 in mouth. Eye 



4.2 to 5 in snout. Head 3.54 to 3.87 in distance from snout to 



anus. (Fig. 5, c.) Muraenichthys fowleri, new species 



3&. Tip of snout rounded, curved on ventral surface and not projecting 



beyond tip of lower jaw as much as diameter of eye, but about as 



much as or less than diameter of impil. 



4a. Front of eye at about middle of length from tip of snout to rictus ; 



distance from front of eye to rictus equals length of snout ; origin 



of the dorsal fin from % to 1 head length behind a vertical 



through anus ; depth 34 to 39 ; head 8.65 to 9.05 ; tip of snout to 



anus 2.43 to 2.7 ; snout to origin of dorsal fin 2.08 to 2.1 ; and 



tail 1.6 to 1.7; all in total length. Depth 3.77 to 4.2; mouth (tip 



of snout to rictus) 3.GG to 4.36, both in length of head. Snout 



1.69 to 2.3 in mouth. Eye 3.5 to 4 in snout. Head 4.15 to 4.3 in 



tip of snout to origin of dorsal. Head 3.4 to 3.56 in snout to anus. 



(Length of specimens lOG and 102 ram.) (Fig. 5, d.) 



Muraenichthys schultzei Bleeker 

 46. Front of eye much behind middle length of mouth, posterior border 

 of eye over or a trifle behind rictus, distance from front of eye to a 

 vertical through rictus contained two to three times in snout ; 

 origin of dorsal fin a little in front of anus to not more than '^/f 

 head length behind anus ; teeth on maxillary in two rows, some- 

 times a little irregular; those on vomer in a single row; teeth 

 on dentary uniserial except a few extra near tip of jaw; those 

 on intermaxillary plato in an irregular ring around a slightly
