SCORPAENIDAE 



125 



from South Africa, but has a smaller eye, wider interorbital region, and somewhat 

 shorter pectoral and pelvic fins. 1 A small specimen (94 mm.) from Gough Island, 

 obtained by the ' Scotia', is very similar to young examples of H. maculatus, but it is 

 possible that this also belongs to an undescribed species. 



Helicolenus lengerichi, sp.n. 



St. WS 742. 5. ix. 31. 38° 22' S, 73 41' W. Small beam trawl, 35 m.: 1 specimen, 88 mm. 



Closely related to H. maculatus and H. lahillei. Depth of body 3 \ in the length, length 

 of head z\. Snout a little shorter than eye, diameter of which is about 3! in length of 

 head and twice the interorbital width. Interorbital region with a shallow groove. 

 Maxillary extending nearly to below posterior edge of pupil. Longest gill-rakers about 

 \ diameter of eye ; 21 gill-rakers on lower part of anterior arch. 5 series of scales between

last soft-ray of dorsal and lateral line. Dorsal XII 12 ; third (or fourth?) 2 spine longest, 

 about \ as long as head. Anal III 5. Pectoral with 19 rays, the 2 uppermost simple, 

 the next 9 branched, and the 8 lowermost simple and somewhat thickened; the fin does 

 not nearly reach the level of the vent. Pelvic about | as long as head, extending about 

 as far as pectoral. Caudal peduncle a little longer than deep. Pale reddish-brown; 

 upper parts of head and body spotted and marbled with darker; an irregular dark 

 blotch at upper angle of gill-opening ; dorsal irregularly marked with dusky ; other fins 

 uniformly pale ; lining of body cavity and branchial chamber black. 



Hab. Chile; Juan Fernandez. 



Described from a single specimen, 390 mm. in total length, the holotype of the 

 species; collected at Juan Fernandez by Dr Lengerich and forwarded to the British 



1 I am indebted to Dr K. H. Barnard of the South African Museum for several small specimens (125- 

 205 mm.) of H. maculatus for comparison with the types of H. lahillei. 



2 This spine is abnormally formed in the holotype.
