NO. 2133. FISHES TAKEN BY "ALBATROSS;' 188S— THOMPSON. 



421 



way below the second dorsal and extending along the sides of the tail; 

 belly with smaller, blunter spinules in a band from the chin to the 

 ventrals, widening behind; teeth tricuspid. 



5. RAJA MAGELLANICA Steindachner. 



One specimen from station 2774, in 17 fathoms, near the eastern 

 entrance of the Straits of Magellan. The measurements do not 

 exactly correspond to those given by Steindachner, but the color and 

 spination are so similar as to leave but little doubt of the correctness 

 of this identification. The interorbital space is one and one-fifth 

 times the longitudinal diameter of the orbit. 



6. PSAMMOBATIS RUDIS GUtither. 



One yomig specimen from station 277S, in 61 fatlioms, near the 

 Second Narrows in the Straits of Magellan. 



7. GALAXIAS MACULATUS (Jenyns). 



Nine specimens from Mayiie Harbor, Patagonia, the measurements 

 of which are given under Galaxias aitcuuaius. They are all strongly 

 colored and differ much in this respect from (/. alpinus. Two speci- 

 mens from the same locality differ in having a much longer head and 

 maxillary, the larger having the head 0.29 and the maxillary 0.11 

 of body length, the smaller having the same 0.28 and 0.10, 

 respectively. These may be contrasted with the measurements 

 given for G. maculatus (under G. attcnuatus). The pectorals and 

 ventrals are as long as the longest of those of the other sjDecimens, 

 but no other striking differences may be seen. The color is in larger, 

 less broken spots, but presents no greater variation from the others 

 than is found within the range of the latter. Without more speci- 

 mens they can not be regarded as a distinct species. 



8. GALAXIAS ATTENUATUS (Jenyns). 



Very numerous specimens from Port Otway, Patagonia. The 

 variation among them is very large and certain of them are inter- 

 mediate in some respects between this species and G. maculatus. 

 One of the principal differences is the length of the head, wliich is 

 much greater in the latter. In the following table the differences 

 are shown by giving the number of individuals having each head 

 length, this being measured in hundredths of total length to base 

 of caudal:
