Castelnau distinguished Aploactisoma schomburgkii from Aplo- 

 aciis lailesii on account of differences in their dentition and fin- 

 formulae, though he noted that the two species were possibly 

 identical. If the specimens referred to below* are correctly 

 identified as A. schombiirgkii, as I believe, these differences do 

 not exist, as they have no palatine teeth, and the fin-formula 

 is variable. I count eight specimens as follows : — D 28-29(xiii.- 

 xiv./14-15; A.12-13(i./ll-12); the length of the anterior dorsal 

 spines is variable, the second being from half to two-thirds as 

 long as the head. 



Logs. — The Australian Museum collection includes specimens 

 from Port Jackson, New South Wales; South Australia; and 

 Western Australia.

D.2-3, 32-33/5; A.2/25-26; P.15; V.3; C.IO. Length from snout 

 to end of bony operculum 3*7-3-9, depth at origin of anal 4-1-4-6 

 in the length to the hypural. Eye 5'2-6-l, snout 4'6-4-7 in the 

 head. Interorbital width 1-2-1 -4 in the eye. Second dorsal 

 spine 3-4, first dorsal ray 2, fourth last anal ray 2-2-1 in the head. 

 Median rays of the pectoral 1-0, ventral l-G-1-9, and caudal 1-5 

 in the head. 



Body moderately deep and robust. Maxillary reaching beyond 

 the hinder margin of the eye. Tentacle of anterior nostril form- 



* One of these is in the old collection of -the Australian Museum, and is 

 entered in the register as a type of the species; it was purchased together 

 with a type of Kurtu>i guUivieri Castelnau, but the vendor's name is not 

 given, though it was possibly Castelnau himself. The other two have 

 been received on loan from Mr. Edgar R. Waite, Director of the South 

 Australian Museum, and belong to the old collection of that Institution. 

 They agree with the description of Aploactisoma schhmburgkii in all details 

 except the dentition, which suggests that this character has been incor- 

 rectly described by Castelnau,
