In the literature we find the following : 



Remaining anatomical features and visceral anatomy. 



In the female the inferior (outer) margins of the two ventrals are united at 

 the base for quite a short distance hut otherwise free of each other; the upper 

 (inner) margins are fused with the abdominal skin, the fusion reaching to the 

 front border of the anus ; in this way is formed the often-mentioned brood-sac. 

 The lining of this sac carries a great number of filaments arranged in longitudinal 

 rows ; most of the filaments take their origin from all the fin-rays except the 

 lowermost (outer) spinous ray, but quite a number form one row along the middle 

 line of the abdomen; the longest and most developed are those of the anterior half 

 of the sac, but along the fin-rays they are found almost to the hind margin of the 

 sac, gradually decreasing in length, the hindmost being very small. 



Part, if not all, of the filaments on the rays contain a slender, undulated or 

 twisted bony axis, an outgrowth from the bone of the ray, as mentioned above 

 under the osteology of the ventrals. This axis only occupies the basal part of the 



* The number 26 is given in the description, 18 in the formula. 



'* These numbers are given for „Sol, bleekeri A. Dum." which I consider as identical with cya- 

 nopterus Blk. 



"■ The number of caudal rays taken from the figure. 



"" Tanaka's species "So/, leptosoma" I regard as a male S. paradoxus. The number of caudal 

 rays is that given in T.'s figure. Also Bi-eekkk's Sol. brachtjurus is in my opinion = paradoxus; no 

 number of fin-rays is stated. Kaui> 1856 has the following numbers for "Solcn. paradoxus" P:27, V:7, 

 Di : 5, Di; 18 — 19, A: 18—19, C: 15, but his "parado.xus" comprises both cyanopterus and paradoxus. 

 His material of 5 specimens is still in the Museum of Paris and contains 2 paradoxus (1 from Isle de 

 France, 1 from the Indian Ocean) and H cyanopterus (2 from New (iuinea, 1 from Isle de France; the 

 latter = "S. bleekeri" Dum.).
