﻿III. ZOOLOGY. 



1. MoUuscan Fauna of New Haven. A critical revieic of all 

 the Marine^ Fresh Water, and Land 3Iolhisca of the region, with 

 descriptions of many of the living animals and of tiro new species; 

 by Geo. H. Pet.kixs, Ph.D. From Proceedings of tlie Boston 

 Society of Natural History, November and December, 1869. — The 

 total number of species given in this catalogue is 162 ; of these 

 97 ai-e Gastero])ods (51 marine); 54 Lamellibranchs (iO marine). 

 Of the 91 marine species 50 are said to occur north of Cape Cod; 

 13 in Labrador; 8 in Greenland; 8 in Europe ; 5 1 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 species 

 recorded from Long L Sound, but not yet found at New Haven, is 

 given at the end. The two new species described and figured are 

 Nassa fretensis (like iVi inbex) and Astarte lutea (allied to A. sul- 

 cata). A new generic name, in errata Tottenia (by error Totten- 

 iana) is proposed for Venus gemma Totten, and Grassivenus 

 instead of Mercenaria for Venus mercenaria Linn., the name, mer- 

 cenaria, being objectionable because properly a specific name and 

 an adjective. Mytilus hamatus Say is referred to Brachydoides, 

 and Pleurotoma hrunnca is proposed for P. plicata Adams. 



The synonomy is far from complete, and although completeness 

 could hardly be expected 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 " Melantho decisa Binney," should have H. & A. Adams 

 as authority, and '• Vicipara decisa Gill " in the synonymy, should 

 be M. 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 (JytJierea Say- 

 ana Conrad, Jour. Phil. Academy, vol. vii, p. 124, 1834; the refer- 

 ence to Gould, " p. 34," should be p. 84 ; " Callista conrexa Say," 

 should be Cytherea ronvexa Say; and finally the correct reference 

 for " Callista convexa'''' is Adams' Gen., ii, p. 425. This species is 

 really a Callista, unless we adopt Komer's subgenus, Caryatis, to 

 which it also belongs. But (.^jurad's grounds for rejecting Say's 

 name, convexa, seem to be insufficient, — at least I am unable to find 

 another species of Callista with the same name. " Mercenaria 

 violacea Stimpson," should be M. violacea Schumacher, " Modiola 

 modiolus Tinn," should read M. modiolus Turton, {Mydlus modi- 

 olus Linn.), and M. harbatus is no doubt a distinct Mediterranean 

 species. " 8ca2)hnrcn transversa Say," shouhl be 8. transversa H. 

 & A. Adams, [Area traiisversa Say). 



The following names, quoted as having Stimpson (Check List), 

 Tryon, Conrad, etc., as authorities, are found in H. & A. Adams' 

 Genera of Recent Mollusca, and some of them, perhaps, in earlier 

 works: — Amycla Goiddiana, A. dissimilis, Tritia trivittata, Ce- 

 rithiopsis Emersonii, Lunatia heros, L. triseriata, Turbonilla 

 interrupta, T. nivea, MelantJiO decisa, Bittium Greenii, Tectiira 

 testudinalis, Martesia cuneiformis, Xylotrya pahnidota. Siliqiut 

 costata, Angulus tenenr, A. polita, Peronea tenia, Macoma fusca, 

 Brachydontes plicatula, Scapharca transversa. v.
