274 MR. G. A. BOULENGER ON FISHES COLLECTED [Mar. 1, 



have been unpleasant. However, they were evidently indigestible, 

 for next day both were found floating in the aquarium. 



One larva of A, grossulariata was refused after being just tasted by 

 one Frog. 



These are all the regular notes made upon the insects eaten by 

 the Frogs, but in addition to the above various other larvae and imagos 

 were given to them. The foUowingimagos were eaten : — E. angularia, 

 V. urticce (both these in great numbers, although they were often 

 refused by individual frogs), Acronycta psi. 



The following larvae were also eaten : — Phlogophora meticulosa, 

 and the hymenopterous Crcesus septentrionalis. 



Although wasps were refused, the common hive-bee was eaten, 

 together with other species of bees (e. g. Andrena nigro-cenea) and 

 many species of Diptera {e. g. common species of Miisca, Eristalis, 

 and Syrphus, Bibio mnrci, &c.) and of spiders (e.g. Epeira diadema, 

 Tegenaria domestica, &c.). All of these were relished and eagerly 

 sought after except the bees, which were generally swallowed, but in 

 most cases rejected afterwards and were found floating in the aqua- 

 rium. Very often I saw the bees (Apis and Andrena) liberated after 

 being held in a Frog's mouth for some seconds, and as soon as the 

 animal began to reject it most violent and active efforts were made, 

 especially with the tongue, in order to get rid of the insect as rapidly 

 as possibly. From the sudden and spontaneous way in which the 

 insect was often rejected after being held in the mouth for some 

 seconds, I was led to believe that the Frog was stung. Earthworms 

 were eaten by some of the Frogs, but apparently without relish, and 

 the majority refused them altogether, and the same was true of the 

 larvae of the commonest Muscidse. Goccinella septem-pitnctata and 

 C. bipuncfata were invariably refused. Cockroaches, Earwigs, and 

 Aphis hedercE were eaten, the latter by very young Frogs,

 Eastern Ecuador. By G. A. BoulengeRj F.Z.S. 



[Eeceived February 7, 1887.] 



(Plates XX.-XXIV.) 



The rich collections brought over from Ecuador by the late Mr. 

 Clarence Buckley in 1880 contained a large number of highly inter- 

 esting and well-preserved Fishes obtained at three localities, viz. 

 Canelos, Sarayacu, and Pallatanga. On the arrival of the collection 

 a set of all the species was selected and retained for the National 

 Museum. The duplicates having been sold by the well-known 

 dealer Mr. Gerrard to other institutions, principally to the Vienna 

 Museum, some of the novelties have already been described by Ur. 

 Steindachner.
