Ectocarpus Dietzie, Harvey, and FE. Hooperi, Harvey. Unfor- 
tunately, the originals of these two species in Herb. Hooper and 
Herb. Harvey are all sterile, and it is practically out of the ques- 
tion that future algologists should ever be able to recognize them 
again, there being nothing specifically characteristic in the sterile 
plants. All that one can say is, that of the two specimens of £. 
Hoopert in Herb. Hooper, one, No. 590, agrees with Harvey’s 
figure in the Nereis in having short spinose ramuli, but No. 55 
does not agree at all with the figure. Exactly what either of 
them is cannot be determined from the original specimens, and £. 
Flooperi,as well as E. Dietzie, should be dropped from the list of 
known L£etocarpi. The original specimen of Lctocarpus lutosus, 
Harvey, from Herb. Hooper, shows that the specimens from 
Wood’s Holl, mentioned in the Marine Alge of New England, 
were correctly determined. 
Codium tomentosum, Stackhouse——A specimen of this species 
is labelled Greenport, L. I., but the locality needs confirmation. 
This alga is common in many parts of the world, and the New 
England coast is one of the comparatively few places where it is 
not known to occur. It appears more probable, seeing how com- 
monly specimens of the species are found in collections, that there 
is an error in the label than that its presence in Long Island Sound 
should have escaped the observation of the numerous collectors in 
that region. 
The specimens of Wrangelia filicina, Harvey, and Hypnea Wur- 
demanni, Harvey, are to be referred respectively to Wrangelia pe- 
nicilata and Eucheuma isiforme as stated in the Nereis. The 
Striaria attenuata of Herb. Hooper is not that species, but Dzc- 
tyosiphon feniculaceus, Greville, and Mesoglota multifida from the 
Same source is Mesogloia divaricata Kuetzing. 
A Study of Solanaceous Anthracnoses. 
The tomato, pepper and egg-plant are three vegetable fruits 
belonging, as is well-known, to the same family (Solanacez) of 
plants. Two anthracnoses are recorded upon the tomato, namely : 
Gleosporium fomoides, Sacc., and Colletotrichum Lycopersect, Chest. 
The pepper has two also, Gleosporium piperatum, E. & E., and | :
