variable in length, position and projection. In only one case were 

 2 closely situated spines found at the soft dorsal origin, the rays of 

 the fin ranging 10 to 12. Only a single oval spine in all the 

 examples, the rays 7 to 10. A young Delaware example shows un- 

 usually short or hardly developed innominate bones. The color 

 pattern is also extremely variable, and in no two examples exactly 

 alike. 



Four examples Cope reported in 1865-, labeled as having been 

 brought from Sukertoppem, Greenland, by Dr. I. I. Hayes, 

 are not Eucalia inconstans, with which he sought to identify them. 

 I subsequently wrongly referred four examples, labeled "Godhavn, 

 Disco Island, Davis Straits" from Dr. I. I. Hayes^ to Gasterosteus 

 aculeatus, which suggests they may have changed labels. 



AULOSTOMIDAE. 

 Aulostomus maciilatus Valenciennes. 



Two from Santa Cruz, W. I. Eye 2^ to 2f in postorbital. 



Aulostomus chinensis (Linne) 



Honolulu, Hawaiian Islands, Oahu, Pacific Ocean. Eye 2| to 

 2f in postorbital. 



FISTULARIIDAE. 

 Fistularia tabacaria LinnS. 



Manasquan, Ocean City, Beesley's Point, Angelsea, N. J.; Rio 

 Janeiro, Brazil; Trinidad W. I.; Banda Point, West Africa. This 

 material shows the variations quite extensively. The characters 

 pointed out by Jordan and Starks in their distinctions for F. 

 petimha and F. depressa are in some instances covered by my mate- 

 rial. However the median ridges on the snout above are slightly 

 divergent anteriorly. In all cases the skin is smooth. 



Fistularia petimba Lacepede. 



Hawaiian and Philippine Islands. I have not found any struc- 

 tural differences for this species, in attempting to distinguish it 

 from the preceding. "Upper lateral edges of snout with few 

 serrations or none" as given by Jordan and Evermann for their F. 

 tabacaria in comparison with "upper lateral edges of snout sharply 

 serrated" for F. petirnba, are surely worthless. The blue spots for
