THE FISHES OF THE JUAN FERNANDEZ ISLANDS 53 
tical or in nearly related species. For most of the genera, to which these spe- 
cies bolong, no representates are hitherto known from the Chilean coast 
(Nos. 14, 15, 30, 31, 32, 33, 34). 
8. Some species can not be included in the above groups. Ladrichthys 
gayi belongs to a genus of Indo-Pacific distribution. C/zlodactylus monodactylus 
(if identical from the different localities) has been stated from three widely se- 
parate localities in the South Temperate Zone. Cadlanthias platei represents a 
genus, which as far as known has a very disconnected range: Juan Fernandez, 
Tasmania, Mediterranean, and Madeira. 
List of the species collected by Mr. K. Bicksrrom, zoologist to the 
Swedish Expedition. 
1. Atherinichthys gracilis Steind. — Chirostoma gracile Steind. 1897, 
l. c. p. 314 (Juan Fernandez). 
Twelve specimens, 87—77 mm. (s. c.). Caught in nets, Masatierra 
Pf, 1917. 
The relative measurement of five specimens, 104—93 mm. tot. length, 
(87—78 s. c.), are as follows: Height in length 81/s—7,3 (6,.9—6,1 s. c.); head 
5,2—5,5 (4,2—4,6 S. c.); eye 3,4—3,1 in head; snout 3,3—3,6; interorbital space 
4,0— 3,5. 
2. Lotella fernandeziana n. sp. — Lof¢ella rhacinus Steind. 1897, 1. c. p.

mos, | ec. p. 208. : 
Two specimens, 155 and III mm. (s. c.); Masatierra *°/g 1917. 
Description of the type-specimen, 155 mm.: 
B. 7, D. 5/58, A. 57, P. 25, V. 9. Height of body 4 %/« im total length, 
4,1 without caudal; head resp. 4,1 and 3,6 in the same. Eye 4,9, snout 3,9, 
and interorbital space 4,4 in length of head. Eye 1,23 in snout and I,zz in in- 
torbital space. Pradorsal region not quite 3'/4 in total length without caudal, 
length of pectoral 1,6 in head. Height of caudal peduncle 23,8 in tot. length 
(s. c.). Longest ventral ray about 1 7/4 in length of head. 
Teeth in upper jaw arranged in an outer row of strong conical teeth and 
behind this a bar of small teeth, which form no distinct rows. In the lower 
jaw the symphysial teeth are arranged as those in the upper jaw. Laterally 
there also is a series of strong, conical teeth, inside of this there are, however, 
no teeth, whereas a series of very small teeth form an more or less disconti- 
nous outer row on the labial side of the large teeth. 
Colour in spirits brownish, lighter on throat and abdomen. Barbel pale 
yellow, only with some traces of a darker pigmentation on its anterior side. 
Lateral line light coloured. Vertical fins blackish brown with a narrow whitish 
edge. Pectorals dusky, ventrals pale yellowish. 
In the smaller cotype the proportions are somewhat different: Height in 
length 5,6 (5,0 s. c.), head 4,3 (3,8), eye 4,1, Snout 4,r, interorbital space 4,7 in
