Lyncodaphnia macrotJiroidcs, sp. n. — Form sub-rectangular, 

 greatly elongated ; length ^ m ; height ^o cm or less ; first antennae 

 long and slightly curved, bordered behind by about ten spines, 

 and terminating in two or three sword-shaped unequal spines and 

 several sense-hairs, about 1 oo cin long; swimming antennae very 

 slender, as in Macrothrix, ,;;/'"' long ; head not marked off by a 

 depression from the body, small and extending below into a blunt 

 elevation for attachment of antennae ; labrum rather large ; eye 

 small ; macula nigra conspicuous but not large ; anterior feet 

 strongly armed with curved spines ; intestine anteriorly is fur- 

 nished with cceca, is twice convoluted, broadened before entering 

 the rectum, and opens some distance beyond the anal setae in the 

 heel of the post-abdomen ; post-abdomen rather slender, toothed 

 behind with a double series of about twelve prominences, ciliated 

 near the anus but distally becoming strong, sharp teeth ; ter- 

 minal claws large, curved only at the end, pectinate and bearing 

 near the base a small and large tooth ; eggs much like those of 

 Macrothrix. Male not seen. 



Occurs in Lake Minnetonka, Hennepin county, Minnesota; 

 rare.— C. L. Hcrrick. 



Food of the Nestlings of Tukdus migratorius. — In this 

 vicinity robins usually rear two broods in a season — sometimes 

 three— and occasionally young birds that are hatched in May will 

 mate and repair the nest in which they were born, or build a new 

 one, and rear a brood in August and early September, thus be- 

 coming parents at the age of about four months. The nestlings 

 of the earlier broods are mostly, if not exclusively, fed upon ani- 

 mal food — insects in all stages of development— while the later 

 broods receive a large share of fruit when in the nest, and after 

 leaving it, so long as they require the attention of their parents. 

 Near the farm-house, or in the village, the old birds take straw- 

 berries, currants, gooseberries, cherries, and the cultivated small 

 fruits generally for their young as well as for themselves, and in 

 the fields and woods thev use almost indi->criminate!v strawberries, 

 blackberries, huckleberr.es, blueberries, and wild cherries for 

 their nestlings, without giving up the use of insects. The latest 

 broods frequently get a taste of early grapes, nor is it uncommon 

 for the parents to carry to their little ones mouthfuls of mellow 

 apples and pears. There are but few small fruits, cultivated or 

 wild, that are not, to some extent, appropriated as food for the 

 nestlings when the parents can get them, and I think from obser- 

 vations of several years that at least one-third, probably one-half, 

 of the food of nestling robins consists of the various fruits in 

 their respective seasons. In the later broods, insects predominate 

 as food during the, first half of their nest -life, the fruits being prin- 

 cipally used during the remainder and until the young are able to 

 take care of themselves.
