an eiiu' l-amelle der Clavicula; am ganzen Hinlerrande sitzen die Basalstücke der Brustflosse. 

 Kine Ziisamincnsctzung dieses Knochens aus mehreren aufzufinden, habe ich vergeblich mich 

 bemüht". 



Siebenhock (29), who has only investigated the nature of the connection of the pectoral 

 girdle to the skull, includes Cenlrisciis in his Group rf, in which all 3 elements of the jiectoral 

 girdle are present; on p. 123 he states, that in this the uppermost element, suprascajudar 

 (i.e. my posttemporal), is not forked, but broad and short; p. 130 he says: "Das Suprascapu- 

 lare bildet die äussere Ecke des Hinterhauptes und hat eine grubenförmige Verliefung zu 

 Anlenkung des Scapulare (my supraclavicle), die bei C. immer noch vom Pleurooccii)itale 

 (my epiotic) begrenzt wird". On PI. V, fig. 9, he gives a figure of the posterior jjortion of the 

 skull and the upper end of the pectoral arch; on p. 131, it is said, that Bosenthal does not 

 seem to have known the "suprasca|)ulare", which is attached to the skull, but only the other 

 two elements. 



14; p. 89 (51): 



Regarding the pubic arch itself I have not found any remarks in the literature beyond 

 the following by Agassiz (lb, p. 272): 



"Les nageoires ventrales n'ofTrent rien de jiarticulier. Mais ce qu'il y a de remarquable, 

 c'est que l'os du bassin auquel s'attache la petite ventrale, est fixé entre les deux osselets 

 styloides de la ceinture thoraciquc; ce qui confirme pleinement l'oijinion de Carus, que cet 

 osselet doit être envisage comme appartenant aux extrémités postérieures, dont il serait une 

 espèce d'iléon".

Whilst the number of rays in the ventral fins is correctly given by many authors, 

 amongst them by Linné (in the formula; but later he says: "Pinnæ ventrales binæ, 4-radiatæ "), 

 Lacépède, Günther, it has nol been noticed as a rule, thai the outermost is a spinous ray; 

 GÜNTHER even maintains the contrary, as he has in his diagnosis of the genus Cenlriscus 



(14 a, p. 518): "Ventrals composed of five soft rays" and regarding the species C.scolopax 



(p. 520) "apparently without spine". On the other hand, a number of American authors credit 

 the ventral fins with a s])inous ray, but with too many soft rays; thus Gill (12a, p. 163): "a 

 spine and several rays", Goode and Bean (13, p. 487) "one spine and seven rays", Jordan and 

 EvERMANN (19, p. 758) "1 spine and 5 soft rays", Jordan and Stahks (20, p. 68) "1 spine and 4 or 

 5 soft rays".

Concerning the internal organs I find in Günther (14a, p. 518) for the genus Ccnii-isciis: 

 ".\ir-bla(lder large; pyloric ajjpendages none". With regard to the branchiæ in the family 

 Cciitriscidœ, which with Günther also includes Amphisilc, it is stated correctly: "four gills 

 and pseudobranchiæ". 



Hyrtl includes Cenlriscus (18, ]). 33) amongst the fishes, in which the right cardinal vein 

 is obviously much larger than the left.
