Pallas (39, p. 33) " roulriim sublus longitudinaliter hieoslaUim & ramcnlonim 



nigrorum tribus ])aribus æquidistantibus barbatuni." His tig. 6 on Tab. IV is bad enough bul 

 better than that of Seba; it shows 3 pairs of lilaments below the snout but the hinder pair 

 at some distance in front of the level of the eye. The slender shape of the snout and of the 

 caudal peduncle ("Pone hos processus ;i. e. the "hump" for 1)2 and A] cauda adtenuatior ' 

 etc.) ])roves sufficiently that his s|)ecies really must be our Solen, paradoxus. 



Bleekek (2 a, p. 308) describing "Solenostoma paradoxum" = our S. ci]anopleius does not 

 mention any cutaneous filaments; but later (2b, p. 52) he states for "Solenostoma paradoxum 

 Lacép. Rafin. ' = our S. paradoxus: "... rostro acuto ... sextuple longiore quam parte gracil- 

 lima alto, inferne multici rrato." 



Kaui' (25, ]). 2) says about his "Solenostomus jjaradoxus '; "Some of the specimens have 

 little skinny lags round the mouth and rostral tube, as re|)resented in Pallas's figure." Of the 

 5 s])ecimens known to Kaup, and by him called S. i)aradoxus (which all belong to the Mu- 

 seum of Paris), 3 are Sol. ciianopterus and 2 Sol. paradoxus. 



2-1 p. 31() [50]. Information about the vertebral column is only given by Güntheh, Bol'- 

 LENc.EU and Re(;an 



GONTiiEii (16 b, p. 151): "The vertebral column is composed of eighteen abdominal and 

 fifteen caudal vertebræ, the vertebne gradually decreasing in length backwards, so that the 

 shortness of the tail is caused not only by the smaller number of vertebræ, but also by their 

 much lesser length. Neural and hæmal spines are developed." Hi:c.an (45 c. p. 8): "The præ- 

 caudal vertebræ have short transverse processes and the caudal vertebræ are much abbre- 

 viated; ribs are absent." BovLEN(iEii (4 c, p. 633): "Anterior vertebræ elongate, without trans- 

 verse processes; no ribs.'

 nageoires non articulés." 



Aboul the number of lin ra\s in the vcntrals and first dorsal most authors agree; 

 only Bleeker gives for S. cijanopterus V = ll, presumably having counted some of the 

 bifurcated rays as two rays, and DuMÉiui. gives 8 rays in the ventrals of the male S. para- 

 doxus. That Skis.\ gives 4 rays in the first dorsal, together with other ap|)arenl mistakes, 

 I think is due to the bad stale of his single, dried, specimen, which his figure clearly 

 proves. The number 16, which without excejition 1 have found in my si)ecimens, I think 

 will prove to be the normal number. I hardly believe that a variation between 12 and 20, 

 as the table on p. 323 [57] shows, would be possible, where a caudal fin is developed and 

 enlarged to such a degree, as is the case in the present genus. In the other fins, where 

 the number (d' fin-rays are greater and their stiucturc weaker, the numbers ai)parently vary 

 slightly.

 p. 379) for Solcu.: "Opercular apparatus reduced to operculum and very few branchiostegal 

 rays." .\1sü Johdan and Snydeu (22, p. 3) repeat for the Lophobranchs: "Gill covers reduced
