REVISION OF PORICHTHYS — HUBBS AND SCHULTZ 485 



The available specimens of this form are unfit to serve as the basis 

 for the proposal of a new name. The examination of material newly 

 collected about Cape San Lucas should solve its status. 



PORICHTHYS ANALIS, new species 



Two specimens of Porlchthys from the Gulf of California present 

 characters that indicate rather conclusively a specific difference from 

 both notatus and margaritatus. They were dredged by the Albatross 

 on March 24, 1889, at station 3017, in 58 fathoms, at latitude 

 29°54'30" N., longitude 113°or0O" W. The holotype, 95.5 mm in 

 standard length and 108 mm over all, is cataloged in the National 

 Museum as no. 46645. The one paratype, measuring 80 and 93.5 mm, 

 is U.S.N.M. no. 106503. 



In number of dorsal and anal rays (tables 1 and 3) P. analis agrees 

 Avith P. myrimteT^ but it has the V-shaped branchiostegal row of 

 photophores characteristic of notatus and its variants as well as 

 margaritatus. When analis is compared with notatus the increased 

 number of fin rays seems particularly significant in view of the 

 apparent decrease southward (from California) in average number 

 of rays. It differs further from notatus in having the pleural row 

 of photophores as in margaritatus continued backward (as smaller 

 organs) from the end of second third of anal base nearly to end of 

 fin. Instead of ending before the end of the large organs of the 

 pleural photophores, the pores and cirri of the pleural branch of the 

 lateral line extend to the caudal fin. The pores in this extension of 

 the pleural line are even stronger than in margaritatus. Furtlier 

 differences between analis and both notatus and margaritatu.s lie in 

 the coloration of the body, head, and fins, as specified in items 66, 

 6c, and U of the key (pp. 475-476). 



Dorsal 11-38 (11-39)^; anal 36 (36) ; pectorals 19-20 (20-20) ; pel- 

 vies 1, 2. Gill rakers on lower part of first arch 16 ( 16) . Palatine teeth 

 caninelike, very slightly curved backward, 7 to 9 in the single series 

 on each side, the anteriormost teeth strongest ; vomerine canines 1 or 2 

 at each outer angle of bone ; rather strong, very slightly curved back- 

 ward; premaxjllary teeth conical; mandibular teeth biserial an- 

 teriorly, with the inner row continued backward as strong canines. 

 Peritoneum brownish black. The coloration of body, head, and fins 

 is given in the key, under item 6(7 (p. 475).
