26. Porichthys porosissimus (Cuv. <t Val.) Gthr. 



{? Batrac7ius porosissimus Cuv. & Val., xii, 501.) 



{Porichthys plectrodon Jor. & Gilb., Proc. TJ. S. Nat. Mus., 1882, 

 291.) 

 The two specimens from South America referred, b}' Dr. 

 Giinther .(Cat. Fishes, iii, 116) to Porichthys poy^osissimus, have 

 the enlarged palatine teeth characteristic of F. plectrodon Jor. & 

 Gilb. The specimen from Vancouver Island mentioned b^^ Dr. 

 Giinther, has small palatine teeth as have all Pacific specimens 

 examined by us. A young specimen from Panama also belongs 

 to P. margaritafus. It is probable that the types of Batrachus 

 jwrosissimus C. & Y., from Guiana and Brazil, really have the 

 palatine . teeth enlarged, although Cuvier & Valenciennes say 

 that " chaque palatin en a une rangie de petites, pointues et 

 inegales." In that case, the Atlantic species would stand as 

 Porichthys porosissimus (C. & V.) Gthr., and the Pacific species, 

 unquestionably distinct, although closely related, as P. ma/rgari- 

 ^a^u*' (Rich.) Jor. & Gilb. 



27. Sebastodes matzubarse (Hilgendorf) Jordan. 



The types of Perca variabilis Pallas (Zoogr. Rosso-Asiat., iii, 

 241= E'pinephehis ciliatus Tilesius), two in number, obtained in 

 the Aleutian Islands, are preserved in the Berlin Museum. 



The smaller of these specimens (6494) belongs to the species 

 for which we have retained the name of Sebastodes ciluitus 

 (Jordan & Gilbert, Synopsis Fish. N. A., 658). For this species 

 the name Sebastes variabilis has been retained in MSS. by Dr. 

 Hilgendorf. 



The larger specimen (8145) is a flat skin of large red species, 

 apparently identical with the Japanese species described by 

 Hilgendorf under the nana^ of Sebastes matzubarae. This view 

 is also held by Hilgendorf. 



As Sebastodes matzubarae has not been hitherto recognized as 

 a North American species, we give the following outline of its 

 characters : — 



Allied to Sebastodes miniatiis. Spines of head low, developed 

 about as in S. miniatus and S. pinniger. Preocular, supraocular, 

 postocular, tympanic, occipital and nuchal spines distinct ; a pair 

 of small coronal spines present, as also a small spine before and 

 one just below eye. Maxillary reaching to posterior border of 

 ej-e. If in head. Both jaws covered with rough, ctenoid scales.
