jaw. The first dorsal spine is elongate, filiform, sometimes extending 

 to the hase of the caudal ; caudal rounded, shorter than the head ; 

 none of the pectoral rays silk-like ; the ventral terminates at a great 

 distance from the vent. Blackish (in spirits), caudal and ventral fins 

 black ; the dorsal filament whitish.

During the printing of this Catalogue, I received that part of 

 vol. xlii. of the Sitzungsberichte of the Vienna Academy in which 

 Herr Steindachner has described a Gobiopsis macrostomus. As I 

 cannot acknowledge Goh'wpsls as a well-founded genus, but refer this 

 species to Gobius, I am obliged to alter the name of the new species 

 described at p. 44, Herr Steindachner' s description being of an earlier 

 date. I therefore propose to caU it Gobius microphiludmus.

Scales of moderate size. The height of the body is one-sixth of 

 the total length, the length of the head two-elevenths, that of the 

 caiidal one-fourth. Snout obtuse, with the anterior profile rounded ; 

 cleft of the mouth nearly horizontal, with the jaws subequal ante- 

 riorly, and with the maxillary extending to below the pupil of the 

 eye. The middle rays of the first dorsal filiform ; the ventral ex- 

 tends to the vent. Reddish-brown, with dark cross-bars. (Gii-ard.)

Kessler's investigations have rendered necessaiy considerable alter- 

 ations in our former account of the Gobies of the Black Sea, for 

 which we relied chiefly on Nordmann. Thus, for instance, we were 

 induced, by the figure quoted, to suppose that this fish belongs to 

 the division of smaU-scaled species ; but Kessler says that it has 44-47 

 scales iu-4:he lateral line. We can scarcely believe, however, that all 

 the specimens examined by the different autliors really belong to the 

 same species when we look at the number of the fin-rays ; these are —
