A CONTRIBUTION TO THE ICHTHYOLOGY

more or less variegated by lighter irregular spots, which some- 

 times are confluent to a light streak. A wellmarked light streak 

 borders the upper margin of the dark bar on the postocular part 

 of the head. On the root of the tail, the bar broadens out and 

 encloses one or more small whitish spots. The caudal fin is 

 barred and variegated with dark and light color, the other fins are 

 hyalin or partly marked with a scattered blackish pigmentation. 

 In the relative measurements there are of course some dif- 

 ferences according to the different sizes of the specimens, as 

 shown in the table below:

According to the table above, the relative measurements for 

 specimens of a length of 58 — 32 mm. are: Height in length 

 (s. c.) 5,9—5; head in length 2,9—2,7; eye in head 5,6—4,6; 

 eye in interorbital space 1,3 — 1,0; eye in snout 1,4 — 1,1; interor- 

 bital space in snout 1,1 — 1,0. 



I am unable to find any closer connection between this new 

 species and the small-scaled Eleotrids before known from Au- 

 stralian waters. On the other hand, it .shows very great resem- 

 blances to Eleotris- herwerdenii Max Web., described by Weber 

 from the Lorentz River in Southern New-Guinea (Notes Leyd. 

 Mus., 32, 1910, p. 238).
