284 report — 1845. 



The base of the caudal is oil-green, the middle parts crimson, and the hinder edge blackish- 

 green. The lips are orpiment-orange. Length of the figure 16^ inches. 



Hab. Canton (Reeves). No specimen. 



In the ' Description of Animals,' &c, which we have repeatedly quoted, there is a sketch 

 (fig. 162) of a Siluroid with a short adipose fin and long anal, which I should have referred to 

 B. bouderius, but for the shortness and number of the barbels, which are stated in the text to 

 be only four ; and only two are shown in the drawing, the maxillary one, which is the 

 longest, being shorter than the head, and the submandibular one still smaller. The nostrils 

 are shown without cirrhi, and the belly is more prominent than that of Reeves's bouderius. In 

 the text (p. 191) the head is said to be "naked and somewhat depressed, the body compressed, 

 smooth and gray. Breast prominent. Ventral in middle of the abdomen. The rays B. 14 ; 

 D. 8; A. 30; C. 28; P. 13; V. 6. Length 20 inches."

 V. 6 ; Cirrhi 8. 



A specimen of this fish exists in the collection of the Cambridge Philosophical Institution, 

 to which it was presented by the Rev. G. Vachell. In the form of the adipose fin and general 

 outline it resembles Mr. Reeves's drawing 203, which is described above under the appellation 

 of Bagrus ? bouderius, but the anal fin is not so extensive. In the hasty record I made of its 

 characters, I unfortunately omitted to note the exact nature of the dental plates on the roof 

 of the mouth, having merely written that the teeth are disposed in broad, close shorn villiform 

 plates ; so there remains an uncertainty as to the genus which cannot be cleared up without 

 a re-examination of the specimen. The mouth is small, and the under jaw is shorter than the 

 snout, which is round. The maxillary barbels are as long as the head and larger than the 

 others ; the interior submandibular pair equal the nasal ones, and are shorter than the exte- 

 rior submandibular ones. They are all slender. The dorsal spine is smooth in front, but is 

 armed with recurved teeth behind. The pectoral spine is also smooth in front, but it is 

 strongly toothed behind. Many short rays are incumbent on the base of the caudal, above 

 and below. Three front rays of the anal are short and graduated, and the last dorsal ray is 

 divided to the base. The specimen is five inches long. In the number of the anal rays this 

 specimen nearly agrees with Arius ocellatus introduced below.

The only one of Mr. Reeves's drawings which has anything like an eyed spot on the adi- 

 pose fin is the one described above as the Bagrus ? crinalis ; but this is scarcely a distinguish- 

 ing mark, as many of the Siluridce have the adipose more or less broadly edged with black.

? Galeichthys stanneus, Richardson. Icon. Reeves, 238 ; Hardw. Malac. 

 177. Chinese name, Seih yu y " Tin fish " (Birch) ; Seih yu, " Tin fish" 

 (Reeves). Seih means also the gingling ornaments of a horse. 

 I have referred this figure to Galeichthys on account of its resemblance to G.feliceps, C. 

 et V. pi. 424, but it may nevertheless be a Pirnelodus. The head seems to be quite smooth 

 above, with less appearance of a casque than in the figure offeliceps above-quoted. The gra- 

 nulations of a narrow interparietal process and a small crutch at the base of the dorsal spine 

 are however shown. The head is wide and depressed, with a rounded snout, and forms about 

 one-fourth of the total length of the fish. The height of the body is equal to rather more 

 than a fifth of the length. The nasal orifices are round without either valves or barbels. 

 The maxillary barbels are shorter than the head, but are longer than the exterior subman-
