BY ALLAN R. MCCULLOCH. 471 



Waite's rather crude figure, which is inaccurate in other details, such as the 

 backward extension of the mouth and the relative length and depth of the head. 

 Localities. — Lord Howe Island; holotype of /. cacatua. Honolulu, Hawaiian 

 Islands. 



Subfamily ELEOTRINAE. 

 Pariglossus rainpordi, n.sp. (Plate xli., fig. 4). 



D.v/17; A.lb; P.18; V.i/4; C.15. Depth at the ventral tins 5.2 in the 

 length to the hypural joint; head 4.5 in the same. Eye 3.5 in the head. Depth 

 of the caudal peduncle 1.7 in the head. Third dorsal spine a little longer than 

 the head. Sixth dorsal ray 1.7, eighth iuial ray 1.5, and pectoral fin 1.4 in 

 the head. 



Body rather elongate, compressed ; head compressed, much deeper than 

 broad. Snout tumid, the mandible in advance of the premaxillaries. Mouth 

 nearly vertical, the maxilla not reaching the vertical of the anterior margin of 

 the eye. Head entirely naked, with several pores above the eye and on the pre- 

 opercular margin. No barbels. Gill-opening lateial and vertical, a little wider 

 than the base of the pectoral; gill-membranes broadly united with the isthmus. 

 Tongue broad, spatulate, its anterior margin rounded. Eye in the anterior 

 half of the head, its diameter much greater than its distance from the end of 

 the snout and equal to the interocular space, which is convex. Premaxillaries 

 with a row of about, seven large outer teeth on each side of the symphysis which 

 increase in size backwards; inside these is a narrow band of minute teeth on 

 each ranms. Mandible with a pair of large canines on each side; a narrow 

 l);uid of minute teetli anteriorly, and a single row of still smaller ones on each 

 side. 



Body largely covered with minute imperfect scales which extend forward 

 to the shoulder, but leave tlie nape naked; they are rudimentary on the ab- 

 dominal surface. No lateral line. A minute genital papilla. 



First dorsal originating just behind the vertical of the middle of the pec- 

 toral; its third spine is longest and filamentous, and together with the fourth, 

 reaches beyond the origin of the second dorsal when adpressed. -Margin of the 

 second dorsal somewhat rounded, the last rays reaching backward to the hypural 

 joint. Anal opposite and similar to the second dorsal. Pectorals rather short, 

 rounded. Ventrals close together, but separate, composed of one spine and 

 four rays; the inner ray is simple and filamentous, but does not reach the vent. 

 Caudal rounded. 



Colour-marking. — General colour light green, with a dark bluish-black 

 marking on the base of the caudal fin. A violet brown band usually extends 

 along the middle of each side, but may be indistinct. A brown spot behind the 

 eye, and several pale blue ones on the cheek and opereidum. First dorsal 

 pinkish, its prolonged rays white; second dorsal dark violet basally, then yellow, 

 with a broad pink border. Anal bright yellow, bordered with pink. Caudal 

 with two broad oblique bars and the median rays pink, the intermediate colour 

 yellow ; the upper and lower edges white. 



Described and figured from a specimen 43J mm. long. Four others 34-44} 

 mm. long, exhibit but little variation, but show that a sixth dorsal .spine may 

 be developed, and there may bo only sixteen rays. 



Affinities. — This species apparently differs from P. taeniatus Regan (Trans. 

 Linn. Soc, Zool., (2), xv., 2, 1912, p. 302) in its colour marking, the dark 

 marking on the tail being undeveloped in that spiecies. Its proportional details 

 also appear to be different.
