PLAGIOGRAMMUS HOPKINSI Bean. 



This species has been known heretofore from only a single indi- 

 vidual which was described and figured by Dr. Tarleton H. Bean a 

 in IN!):]. It was caught along with other species in the tide pools 

 near Pacific Grove by students of the Hopkins Seaside Laboratory 

 and given to the representatives of the U. S. Fish Commission, who 

 were then making a collection for the World's Columbian Exposi- 

 tion. Last summer, late in July, the writer obtained six specimens 

 varying in length from 65 to 190 mm. from the outlying pools at 

 low tide, opposite the light-house near Pacific Grove, perhaps not 

 far from where the species was first taken. 



The skin of the head is rather thick and soft, and when shrunken 

 by the preserving fluid lies in wrinkles and folds, forming a slight 

 supra orcular rim and partly concealing a low crest which extends 

 from the interorbital region forward on the snout. There are 6 

 branchiostegals. The dorsal spines number from 37 to 41, the anal 

 lavs (spines 2) 26 to 29. The membranes of the fins are very thick, 

 and the rays of the pectorals, ventrals, and anal are considerably 

 broadened and thickened toward the tips. There are 43 vertebrae. 

 The specimens in hand show no " subpentaginal plate-like bodies" 

 on the ventral surface, but there are 9 or 10 areas inclosed by branches 

 of the lateral lines, which differ in no way from other parts of the 

 body surface. The "abdominal ridge' 1 (a median line of mucous 

 pores), also mentioned in the original description, leads one to think 



" T. H. Bean, Proc. U. S. Nat Mus., XVI. 1893, p. 699, and Jordan and Ever- 

 liiann, Bull. 47, U. S. Nat. Mus., p. 2-128; "Monterey, California; a few speci- 

 mens dredged among the rocks " is evidently a mistake.
