Fakran — Seventh Report on the Fishes of the Irish Atlantic Slope. 127 



As noted above under T. trachyrhynchus, specimens of Irachyrhynchus, 

 which should probably be referred to 2'. Murrayi, though recorded at the time 

 as T. tradliyrhyiichus, were taken on tlie following stations: —

Only one specimen, the type, whicii is now in the Britisli Museum collec- 

 tion, has been taken by the Hclga, under circumstances which leave it in 

 doubt whether the capture was made in midwater or at the bottom. It was 

 cauglit in August, 1906, in a Petersen pelagic fish trawl about 90 miles off 

 the S.-W. coast of Ireland, .soundings 800 fathoms. Tiie net was used with 

 .800 fathoms of warp, and was estimated to have iished at 700-750 fathoms, 

 but it must, during some part of the haul, have touched tiie bottom, as it 

 brought up some fragments of mollusea and bottona-living Crustacea. 



Tiie only other kiiown species of the genus, L. pinnahis, was first taken at 

 the surface in the S. Atlantic, and very small specimens (2-4 ems.) have since 

 been captured by the Valdivia in vertical nets lowered to 2,000 metres over 

 .a depth of about 5,000 metres. These facts seem to indicate that the genus 

 is a pelagic one, which may account for its apparent rarity. The following 

 description and the tables of measurements and comparison with Z. pinncdus, 

 including the foot-note, are taken without alteration from the paper by Mr. 

 E. W. L. Holt and Mr. L. W. Byrne (1906) in which the original specimen is
