Body ratliei' elongate, covered with small or moderate sized scales, 

 which may be wholly cycloid or lai'gely ctenoid ; lateral line curved down- 

 ward to the middle of the body, formed of simple tubes on enlarged scales. 

 Head naked, eyes large, snout conical, with an oblique profile. A broad 

 patch of teeth in the fi'ont of the premaxillaries, the anterior ones largest, 

 curved and subulate ; mandible with similar but larger teeth, and some 

 curved canines or subcaniniform teeth on the sides ; a narrow curved band 

 of teeth across the vomer. Dorsal fin commencing on the neck, with 

 about 3/14-16 spines, the three anterior ones separated from the othei^s ; 

 second dorsal witli about twelve simple rays. Anal long, with about 21-23 

 rays. Pectoral well developed, with thick simple rays in the lower half. 

 Venti'als jugular, with two thick and one slender ray. Caudal rounded. 

 Gill-membranes forming a free fold across the isthmus, with six bra)ich- 

 iostegals; pseudobranchiae present. 



The inclusion of Trijiten/ijliuii marmoratimi, Macleay, in this genus 

 necessitates the expansion of its charactei'S relating to tlie squamation and 

 dentition. The scales are wholly cycloid in L. Implodartijlus and largely 

 ctenoid in 7'. murmoratiu)/, while the latter species has larger and more 

 numerous teeth than the genotype. The two are so similar in all major 

 characters, however, that they ai-e evidently congeneric. 



a. Scales small, cycloid. Teeth smaller, the lateral premaxillary ones not extending 

 much behind the level of the median patch ; small caniniform teeth on sides 



of mandible haijlodartyJus. 



aa. Scales larger, ctenoid above, cycloid below. Teetli larger, lateral premaxillary 

 ones extending well ])pliind the level of the median patch ; mandible with 

 curved canines laterally dki nnoralus.

The identity of L. r/ei)iiii(ih(n and L. haplodacti/lus has already been 

 noted by McCuUoch.- The holotype of Macleay's species agrees in all 

 details with Steijidachner's description and figure. 



Hal. — Steindachner'fi type was said to have been obtained at Rock- 

 hampton, Queensland. Ogilby has recognised the species in Moreton Bay, 

 and it extends southward to Vmt Jackson, where it is veiT comnnni.
