snout, and reaching to or beyond the thirtieth ray of the second dorsal; 

 second dorsal almost continuous with the first, its anterior rays longest 

 and not diminishing rapidly in size toward tail ; anal inserted under ninth 

 ray of second dorsal, its rays much shorter than those of dorsal, and situ- 

 ated about same distance apart; pectorals inserted under anterior portion 

 of first dorsal, first ray much i)roduced, extending more than halfway 

 from its insertion to tip of tail; ventral origin slightly behind origin of 

 pectoral, under third branched ray of dorsal, its first ray much enlarged, 

 extending more than halfway from its insertion to tip of caudal, its length 

 2^ times in total length; branchiostegals 7. Color yellowish gray, abdo- 

 men bluish. This form is closely allied to B. multiJiUs, described by Giin- 

 ther irom oif the Philippines (Challenger Report, xxii, 155, pi. 42, fig. 

 B, 1887), which, however, appears to have a smaller eye, less elongate fila- 

 ments, and ventrals inserted in advance of the first dorsal, while the anal 

 appears to be further back, under the twelfth or thirteenth ray of second 

 dorsal. Both species are provided with long, slender barbels; in other 

 respects they are closer to B. cottoides, the typical species, than to B. mac- 

 rops. (Goode & Bean.) Deep waters of the Gulf of Mexico, in 525 to 739 

 fathoms, (longus, long; filum, thread.)

Body compressed, with tapering tail. Mouth large, terminal. Dorsal 

 fins continuous, both elevated anteriorly; anal divided, the anterior por- 

 tion elevated, the posterior low. Teeth in each jaw biserial, the outer 

 much enlarged, vomerine teeth present. Bones of head soft and cavernous. 

 Eye large. Gill membranes connected anteriorly, free from the isthmus. 

 Gill rakers slender, rather numerous; vent in anterior third of length. No 

 pseudobranchi;e. Branchiostegals 7. No barbel. Pectorals and ventrals 

 both 1)elow first dorsal. Scales thin, cycloid, deciduous. Deep seas. 

 ("This remarkable genus is named in honor of Dr. Franz Steindachuer, 

 Gustos of the Imperial Zoological Museum of Vienna,'" one of the ablest 

 naturalists of the century.) 



* "Steindachneria, a Macruroid with a high differentiated first anal spine." (Goode & 

 Bean.) 



t As the original diagnosis of the Macrourid genus Steindachneria, although very short, 

 is correct and sufficient for identification, the name in ((uestion should bo retained for it 

 rather than Sfeindachnerella, and the Silurid genus Steindachneria, Eigenmann should 

 receive a new uame.
