1. Molluscan Fauna of New Haven. A critical review of all 
the Marine, Fresh Water, and Land Mollusca of the region, with 
descriptions of many of the living animals and of two new species; 
by Gro. H. Perkins, Ph.D. From Proceedings of the Boston 
Society of Natural History, November and December, 1869.—The 
total number of species given in this catalogue is 162; of these 
97 are Gasteropods (51 marine) ; 54 Lamellibranchs (40 marine). 
Of the 91 marine species 50 are said to occur north of C ape Cod; 
13 in Labrador; 8 in Greenland ; 8 in Europe; 51 extend to South 
Carolina and some of them farther ; 37 occur in the Post Pliocene; 
26 in the Pliocene; 19 in the Miocene. A list of 65 es 
recorded from Long FL Sound, but not yet found at New Haven, 
given at the end. “The two new species described and figured are 
Nassa. fretensis (like V. vibex) and Astarte lutea (allied to Al. sul- 
cata). A new generic name, in errata Zottenia (by error Totten- 
tana) is proposed for Venus gemma Totten, and Crassivenus 
instead of Mercenaria for Venus mercenuria Limn., the name, mer- 
cenaria, being objectionable because properly a specific name and 
an adjective. Mytilus hamatus Say is referred to Brachydoxtes, 
and Pleurotoma brunnea is proposed for P. plicata Adams. 
The synonomy is far from complete, and although completeness 
could hardly be expec ‘ted in a catalogue of this kind, yet it seems 
desirable to give, if any, such references as are necessary to 
explain the nomenclature adopted and the principal synonyms in 
all cases. But besides want of completeness there are many posi- 
tive errors that are scarcely excusable even in a local list. In 
looking it over casually the following errors were noticed, besides 
others of less importance. 
Thus “ Welantho decisa Binney,” should have H. & A. Adams 
as authority, and “ Vivipara decisa Gill” in the synonymy, should 
be MW. decisa Gill, instead of omitting the reference entirely (as in 
errata), for Prof. Gill was the first. to correctly limit the two 
genera, as found in this country. 
The “ Cytherea Sayii Conrad,” p. 147, should be Cytherea Say- 
ana Conrad, Jour. Phil. Academy, vol. vii, p. 124, 1834; «he refer- 
ence to Gould, “ p. 34,” should be p. 84; & Cullista convexa Say,” 
should be Cytherea convena Say; and finally the correct reference 
for “ Callista convexa” is Adams’ Gen., 1, p. 425. This species is 
really a Callista, unless we e adopt Romer’s subgenus, Caryatis, to 
which it also belongs But Conrad’s grounds for rejecting Say’s 
name, cunvexa, seem to be insufficient —at least Lam unable to find 
another species ‘of Callista with the same name. “ Mercenaria 
violacea Stimpson,” should be M. violacea Schumacher, “ Modiola 
modiolus Linn,” should read JZ. modiolus Turton, ( Myrilus modi- 
olus Linn.), and M. barbatus is no doubt a distinct Mediterranean 
species. ‘“ Scapharca transversa Say,” should be S. transversa H. 
& A. Adams, (Areu transversa Say). 
The following names, quoted as having Stimpson (Chee ‘k List), 
Tryon, Conrad, etc., as "authorities, are found in H. & A. Adams’ 
Genera of Recent Mollusc: 1, and some of them, perhaps, in earlier 
works :—Amycla Gouldiana, A. dissimilis, Tritia trivittata, Ce- 
rithiopsis Emersonii, Lunatia heros, L. triseriata, Tur bonilla 
interrupta, T. nivea, Melantho decisa, Bittium Greenti, Tectura 
testudinalis, Martesia cuneiformis, NXylotr ya palmulata, Siliqua 
costata, Angulus tenera, A. polita, Peroneu tenta, Macoma fusea, 
Brachydontes plicatula, Scaphureca traunsversa. Vv.
