filaments were branched. He said with reference to one of his examples — 

 " The lure ends in a flattened disc, the skin of which is prolonged into two 

 horns and eight elongated tentacles." A drawing of the lure is given, 

 and the filaments are branched in the following manner: — Left side, (1) 

 4 branches, (2) 4 branches, (3) 2 branches, (4) single; right side, (1) 2 

 branches, (2) 4 branches, (3) 2 branches, (4) single. In another specimen 

 the lure had, in addition to the two terminal horns, nine filaments, branched 

 as follows : — on one side, (1) 2 branches, (2) 3 branches, (3) 2 branches, 

 (4) 2 branches, (5) single, — on the other side, (1)4 branches, (2) 4 branches, 

 (3) 2 branches, (4) single. Each branch had a swollen clear tip. Still 

 another of these anglers had a lure bearing six filaments, with a single 

 long terminal tentacle on the disc. Liitken did not think that one 

 should search for specific characters in the lure, which is evidently variable. 

 He said that the tips of the filaments were silvery and possibly phosphor- 

 escent. Liitken discusses the question as to whether Himantolopfms 

 rheinliardti is distinct from Himantolophus greenlandicus, Eheinhardt.* 

 The latter was described from a damaged specimen. Its lure, which is 

 shown by Liitken, is very similar, but it had eleven filaments in addition to 

 the two terminal horns. 



There would probably have been no doubt as to the identity of Rhein- 

 hardt's and Lutken's species if the number of fin-rays given by the former 

 had not diverged comparatively widely from those determined by the latter. 

 I give here a table comparing these data in respect to the Danish and 

 Aberdeen specimens : — 



Comparison between Himantolophus greenlandieus, Reinh., Himan- 

 tolophus rheinliardti, Liitken, and the Aberdeen specimen in respect 

 to the number of fin-rays.

There is no doubt that the Aberdeen specimen belongs to Liitken's 

 species. 



The Occurrence of the Pilchard (Clupea pilchardus) off Aberdeen. 



A pilchard, 9 inches (22-5 cm.) long, was caught in a herring net 

 27 miles E.S.E. of Aberdeen on September 1, 1905. 



A Lophius piscatorius with One Eye. 



This angler was presented by Mr. Eunson. It is shown reduced in 

 fig. 1. The fish was, except for the absence of the left eye, externally 

 normal, but the head was slightly asymmetrical, as is indicated by the 

 shape of the mouth. In the drawing only one sensory -olfactory 

 process (sp) is shown on the upper lip. The other was probably absent 

 although no written note was made of this point. When the skin was dis- 

 sected off the top of the head in the region of the orbits (fig. 3), two main 

 muscles were exposed, viz., a transverse muscle, ra., and a longitudinal 

 muscle, M. On the blind side a portion of the longitudinal muscle, if 11 , 

 is inserted in the fascia of the orbit, while the remainder of the muscle, M l , 

 has some strands inserted in the same region. The two tubercles of the 

 frontal which form the upper border of the orbit are expose^ on the normal
