82 NOTES ON DERWENT KSTUAHY FISHES, 



length of the first of the second anal, while McCulloch 

 shows his two anal spines as being half the length of the 

 first spine of the second anal. 



a. This specimen does not show either of these 



two spines of the first series, as a first series 

 of small spines, but rather has them so de- 

 veloped as to be part of the second series of 

 the anal fin, thus making a fin of only one 

 series. The ventral is made up of two con- 

 spicuous and a third barely visible ray, being 

 a young fish (2.5 inches). It is normally 

 marked in -pale rufous brown with seven deep 

 brown bars, not including the intermittent 

 bar of the peduncle. 



As the first three anal rays are subequal, making 

 the first anal absent, I conclude this speci- 

 men isi a variety : D. iii. : xxxii. : 4. A. 26. 



b. The second specimen of interest (Hobart, 



2 — 8 — 09) measures 4.4 inches in length 

 The colours and markings agree with Richard- 

 son's figure, already referred to. The vari- 

 ance lies in the dorsal fin, which shows ii. : 

 xxxiv. : 4, A casual glance at the spirit 

 specimen v/ould indicate that the third spine 

 has joined the second series, leaving a defin- 

 ite distance between them, and with the web 

 joined in the ordinary manner to the first 

 ray of the second dorsal. A lens shows it 

 agrees with the second ray of the second 

 series. So far the species has always siiown 

 U. iii. : xxxii. -xxxiv. : 3-5. 



In addition, the first anal in size more nearly 

 approaches the second. Thus the first anal is 

 variable. 



3. TmPTERYGiUM CLARKEi, Mortoii. — The only record so 

 far is Bass Straits (Clarke Island), and the type is not 

 available for comparison. 



I captured some twenty specimens of varying ages 

 amongst the piers of Hobart in August, 190y. They repre- 

 sented young and adult, ranging between 1.5 and 3 inches 

 in length. As with the other two blennies, the}'' were feed- 

 ing among the mussels of the piles.
