334 FISHES FROM BRAZIL JORDAN. 



FISHES FROM PATAGONIA. 



Besides these species from Bahia and vicinity, a collection contain- 

 ing- four species from Patagonia was sent with them for identification. 

 Tliesc species are the following: 



1. Psammobatis rutrum, sp. uov. 



Taken near Cape San Matios, 42° 24" S. lat., 01° 38' 30" W. long, 

 at a depth of 43 fathoms. Station 2678. Dredged on January 14, 1888. 



Allied to Fsammohatis rudis Giinther. Snout short, very ijluntly 

 rounded, its tip ending in a short, sharp, abrai)tly mucronate, fleshy 

 tip, this exserted tip not quite half length of eye. This tip is the ex- 

 serted snout which separates from each other the ti])s of the pectorals. 

 Length of snout Irom mouth to the base of tip of snout not quite twice 

 width of clett of mouth. Length of snout from eye is 3J times interor- 

 bital space. Snout soft in substance, the rostral cartilages inconspicu- 

 ous, the area between the pectorals translucent, broadly triangular. 

 Disk just as broad as long and about one-fifth longer than tail, its out- 

 lines all rounded. •'■ piracle considerably shorter than eye. Eye rather 

 large, its length greater than interorbital width. Nostrils each with a 

 conspicuous infolded tube-like flap; ventrals deeply notched on the side; 

 the first rays thickened and i)roduced. Tail with a distinct lateral fold. 

 Dorsals moderate, close to the end of the tail, which has a well developed 

 caudal, separate from the dorsal. Back and tail with a median series 

 of strung spines, the strongest being at the shoulder; two irregular 

 series on each side of this, the spines smaller than those of the median 

 row; some additional spines on shoulder; series of stout spines above 

 each eye ; snout and anterior* part of pectorals with small spines in 

 numerous series ; a patch of small spines on posterior i)art of pectoral ; 

 a large patch of spines still smaller and more closely set on ventral. 

 Snout smooth below. 



Color light brown, everywhere thickly speckled and freckled with 

 blackish in fine pattern ; each pectoral with about a dozen small round 

 spots of the ground color, smaller than the eye, and each surrounded 

 by a dark ring. Some of these spots are obscure and fade into the gen- 

 eral coloration of the body. Upper i)art of eye spotted ; middle part of 

 snout with a large, triangular, translucent area. Some faint dusky 

 spots on lower side of the outer margin of pectoral. This species is 

 known from a single female specimen, llj inches long, the tail 5J, 

 dredged by the Albatross off Cape San Matios, on the east coast of Pat- 

 agonia. This species differs from Psammobatis rudis in having median 

 row of spines instead of a median groove, in the different coloration, 

 and the generally rougher disk. 



2. Acanthistius patachonicus (Jeuyns). 

 Eight large specimens. 



Head 2^ in length (3i with caudal); depth, 2i^o iH) D- XlII, 15, A. 

 Ill, 8.
