specimen reported as Trachyscorpia sp. (Chirichigno 

 1974). The specimen was collected off Peru at lat. 

 13°57.2'S and long. 76°42'W in 580 to 600 m. Esch- 

 meyer (pers. commun.), who has examined the specimen, 

 finds no obvious difference between it and T. crista- 

 lata from the Atlantic. If Eschmeyer (1969) is correct 

 in the placement of Trachyscorpia near Sebastolobus 

 in the subfamily Sebastolobinae, its larvae can be ex- 

 pected to share some of the features of Sebastolobus 

 larvae.

or illustrations of the developmental stages of Scor- 

 paenodes. 



Distinguishing features.— Scorpaenodes larvae dif- 

 fer from all other known Scorpaenidae except Sebas- 

 tolobus, in having prominent crestlike parietal ridges 

 that terminate in double spines, the posterior (nuchal) 

 spines being more prominent than the anterior (parietal) 

 spine; in larvae of other known scorpaenid genera, if two 

 spines are present on the parietal ridge, the second is 

 smaller and subjacent to the first. Scorpaenodes differs 

 markedly from Sebastolobus in melanophore pattern 

 and in degree of development at comparable sizes. Newly 

 hatched Scorpaenodes larvae have a series of about a
