THE VOYAGE OF H.M.S. CHALLENGER. 



Fig. 64. — Lucifer reynavdii, young, from a drawing by 

 Dr. v. Willeuioes Suliru. Lettering as before. 



development, but the hairs at the extremity 

 of the telson are of a less spinous appearance. 



The next drawing to which I have to 

 refer in the development of the species of 

 this genus is one of melancholy interest. 

 It has no date attached, and there are no 

 notes relative to its size and proportions, as 

 all others of Suhm's drawings have. It is 

 labelled by another hand :— 



" The last drawing made by E. von 

 Willemoes Suhm. Development of Leucifer 

 reynaudii." 1 



The figure is carefully drawn and all its 

 details strictly preserved. It was evidently 

 a labour of love to Willemoes Suhm, and is 

 here faithfully reproduced, one-third smaller 

 to bring it within the compass of the page. 

 The animal in this stage is evidently as- 

 suming its permanent characters, but the 

 antennal somite is still shorter and more 

 robust than in the adult. It is evidently 

 the same form as Dana 2 has described and 

 figured as Lucifer acicularis. 



The rostrum, which in the previous 

 specimen was subequal in length to the first 

 joint of the first pair of antennas, now 

 reaches but little beyond the acoustic organs 

 at the base of the same pair of antennae; 

 the antero-lateral angles are still con- 

 spicuous points, but less so in proportion 

 than in the younger stages. 



The ophthalmopoda are large and well- 



1 Although there were neither figures nor notes 

 attached to this drawing, I have convinced myself', by- 

 comparison with the mounted specimens which were pre- 

 served and labelled by von Willemoes Suhm, that the 

 separate figures in the text relate to the same specimen from 

 which this drawing was taken.
