Synodus. This fact may indicate an additional character by which 

 to distinguish the order Haplomi, and that Boulenger is right in 

 referring Aulopus and Synodus to this order. 



Starks finds that the close resemblance of the barbels in Polymixia 

 to those in Mullus and Upeneus has no phylogenetic significance. 

 While the organs in the two cases look much alike, they are devel- 

 oped in quite different fashion. 



In Polymixia each barbel is suspended from the hypohyal, where 

 three short, rudimentary branchiostegals curve around its thickened 

 base. In Mullus and its relatives, the barbel is the extreme tip of 

 a slender ray of bone attached to the end of the ceratohyal, and 

 without relation to the branchiostegals. 



In the Bulletin of the U. S . Fish Commission (1902, published 

 1904), Professor John O. Snyder gives a list of the shore fishes 

 taken by the " Albatross " expedition in 1902. Two hundred and 

 twenty-seven species are recorded, with excellent figures of 25 new 



(1889) and Jordan and Evermann (1901). Two new genera are 

 described, Veternio, a toothless Conger eel, and Collybus, a genus of 

 BramidiE. 



In the Bulletin U. S. Fish Commission (for 1902, published in 

 1904), Dr. Jordan gives a list of species of small fishes from coral 

 pools, taken at the Tortugas, Florida, by Dr. Joseph C. Thompson, 

 U. S. N., now surgeon of the K\hzixo%i:'—Ctenogobius tortugce, 

 Gnatholepis thompsoni, Elacatinus oceanops, and Ericteis kalisherce. 



in which group another genus, Adds (moord), is detached from 

 Malacoctenus. 



Chaetodon bricd is shown to be the young of Chu todon capistratus, 



with D. megakpis. The rare Holocentrus sicdfer (Cope 1871)15 

 again recorded. 



Mr. Henry W. Fowler, now of the Academy of Natural Sciences 

 at Philadelphia, has in the Proceedings oi that institution (1903)3 

 number of papers on fishes largely of the Pacific Ocean. Of 



from Italy ; Atherinomorus, a new sub-genus for the West Indian 

 Atherina laticeps, Protistius semotilus Cope redescribed. This genus 

 is allied to Atherinopsis, but has only a single dorsal spine. Gas- 

 tropterus Cope is the same as the later Pisciregia of Abbott.
