52 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 9 



dividing membranes do not extend so far dorsally. P. starksi is similar to 

 S. elcapitanensis in the confluence of the median lateral cristae over the 

 anus, in the division of the brood pouch, and in the absence of the anal 

 fin; but it differs in that the adult female of the latter does not have a 

 conspicuous development of the anal papilla and in that the median and 

 ventral cristae of the latter are very pronounced. The only mature female 

 of 5 paratypes in the Stanford collection (No. 2686) has the phallic 

 papilla retracted ; this may explain the oversight of Jordan and Culver in 

 failing to call attention to this obvious structure. 



The material examined consisted of 10 specimens (2 males and 8 

 females). 



BRYX,* new genus 



Type species. — Bryx veleronis, new species 



Diagnosis. — Genus of Corythoichthys-like pipefishes characterized by 

 (1) smooth head as in Syngnathus; (2) short snout; (3) trunk and tail 

 cristae with inter-ring indentations and with plates roughened, both as in 

 CorytJioichthys; (4) dermal covering of pouch of brooding male widely 

 agape thus exposing eggs in ventral midline; (5) eggs arranged longitu- 

 dinally in 2 regular rows; (6) all prominences very slightly if at all 

 crenulated; and (7) anal fin absent. 



Discussion. — Including Bryx, there have been described in the litera- 

 ture 3 genera of pipefishes very closely related to Corythoichthys; they 

 are Bhanotia, Bhanotichthys, and Bryx. 



Hora (1925, Rec. Indian Mus., 28(6) :463) with material consist- 

 ing of one male specimen of Corythoichthys corrugatus Weber described 

 a new genus of pipefishes, Bhanotia; this genus was characterized by the 

 following differences when compared with the more typical members of 

 Corythoichthys: (1) a brood pouch in which the skin folds met in the 

 midventral line; (2) eggs few, large, and arranged in 2 rows; (3) ser- 

 ration of all prominences on the head and body; and (4) a short snout 

 provided with spines on the dorsal surface. 



Parr (1930, Bull. Bingham Oceanogr. Coll., 28(6) :27) correctly 

 points out that ( 1 ) Hora has accepted Duncker's definition of the genus 

 Corythoichthys as well as his selection of the genotype, C. conspicillatus 

 Jenyns; and that (2) this selection constitutes a violation of the Interna- 

 tional Rules of Zoological Nomenclature, since the genotype had already
