D.xiii/18 ; A.ii/14 ; P.i/20 ; V.i/5 ; C.13. L.lat. with 29 tubes and about 
8 punctured scales. L.tr. 6/1/13. 
Head (35*5 mm.) 3*1 in length to hypural joint (112). Depth of body (65) 1-7, 
and depth of caudal peduncle (21) 5*3 in same. Eye (10) 1*3 in interorbit (13) and 
3*5 in head. 
Upper profile of head steep, convex ; lower similar but less steep. Head 
much higher than long, much longer than broad. Eye rather large. All opercles 
entire. Preorbita) margin slightly excavated though not definitely notched. Jaws 
subequal, lips fleshy. Maxillary not reaching vertical of eye. A single series of 
small compressed teeth in each jaw. Gill-membranes united across isthmus. Head 
densely scaled except anteriorly, around mouth, on chin and anterior half of 
suborbital, where there are naked areas with scattered pores. Auxiliary scales, 
many of them rudimentary, on top of head and sides of nape. 
Body ovate, compressed, covered with small ciliated scales which are largest 
on anterior portions of sides and extend to the distal portions of all the unpaired 
fins, forming dense sheaths ; they cover the basal part of the pectoral and extend 
along some of its membranes, but there are no scales on the ventrals. Lateral line 
well arched, its tube-bearing scales with lobe-like edges. Vent before the anal fin, 
with a minute papilla. 
Dorsal originating in advance of pectorals and ventrals and terminating 
behind anal. Membranes of first dorsal produced into little pencils. Fourth to 
ninth spines longest, subequal. Soft dorsal high, pointed, the seventh and eighth 
rays longest, the last minute and divided. Anal spine longer than any of the dorsal 
spines and very strong ; anal fin lower and shorter than soft dorsal, the seventh 
ray longest and the last short and divided. Pectoral somewhat pointed, longer than 
head, slightly shorter than ventrals whose first rays are filamentous and reaching 
anal fin. Caudal lobes rounded, the upper longer. 
Colour, after long preservation in alcohol, fairly uniform brown, a little darker 
on all the fins except the pectorals, which are lighter. No white opercular patch. 
Described from the holotype, a unique specimen, 112 mm. in length to hypural 
joint, or 6 inches in total length. (Austr. Mus. Regcl. No. I. 13144, originally 
labelled “ Parma microlepis , var.”) 
Locality . — Rottnest Island, West Australia. Presented by the Fisheries 
Department of West Australia. 
Named in honour of the late A. R. McCulloch, who drew, whilst still in his 
teens, the accurate and beautiful figures of the allied Parma microlepis showing 
its variations with growth. 52 
Parma \ mccullochi is the western congener of P. microlepis Gunther, 53 
apparently differing from that species by having a more declivous profile, smaller 
scales, and longer pectorals.
