FISHES FROM NORTHEASTERN PACIFIC — CHAPMAN 529 



tegal membrane and is farther from the second than the second is 

 from the third ; the second, third, and fourth are separated by approxi- 

 mately equal interspaces. The VLO is about the same distance from 

 the lateral line to the base of the ventrals. There are four or five VO, 

 all on the same level and separated by nearly equal intervals. The 

 SAO form an angle of about 100°. The upper one is separated from 

 the lateral line by a distance only slightly greater than its small dia- 

 meter; the second is halfway along a straight line between the upper 

 SAO and the most posterior VO ; the third is far forward, nearer to a 

 perpendicular through the second VO than one through the third, and 

 it is sUghtly below the level of the second SAO. The AO are in two 

 distinct series 6-8 + 7-8. Where the PRC are confluent with, the 

 posterior series of AO they have been counted as four, in accordance 

 with the method of Parr (1928, p. 77). The remainder of the series 

 has been counted as AO posteriores. The first AO anterior is a little 

 below the level of the rest of the series; the others are all on the same 

 level. There are two POL the dorsal one touching the lateral line 

 and lying over the interspace between the two series of AO; the ventral 

 one in on a line between the dorsal POL and the last photophore of 

 the anterior AO series, nearer to the latter than to the former. There 

 are four PRC. The ventral three are close together and He in a gentle 

 arc curving upward from the level of the AO. The dorsal PRC is 

 separated from the ventral three by a wide interspace and Ues directly 

 on the end of the lateral line. The PRC are usually separated from 

 the AO posteriores but in some specimens on one or both sides the two 

 series are confluent. There are luminescent scales both supra- and 

 infra-caudaUy on all specunens. The supracaudal series (3 to 5 

 scales) is always shorter than the infracaudal series (5 to 8 scales). 

 While these luminescent scales are not so well defined as in the species 

 of Mydophum, their boundaries can be made out in each case. There 

 are no other such luminescent scales on any other part of the body or 

 head. There are no photophores above the lateral line. 



Remarks. — Lampanydus micropundatus does not appear to be 

 especially close to any other species in the genus. If the phrase 

 "PRC distinctly separate from AO" be eliminated from A, I in Parr's 

 key (Parr, 1928, p. 78) this species will fit into the group containing 

 L. nicholsi, L. braueri, L. maderensis, L. townsendi, and L. warmingi. 

 It should be included under a separate division C, under A, I. This 

 division C should read "Only four PRC. Four PO." The character 

 "four PO" will serve to separate this species from those listed m the 



group above. oi, i ++ 



Lampanydus micropundatus has been taken off Queen Charlotte 

 Sound, off the west coast of the Queen Charlotte Islands, off Prmce 

 of Wales Island, off Portlock Bank, and off Albatross Bank. 'Off 

 is necessary in the above phrases because it has been on each occasion
