Middendorfia Cpr. (Dawsonia Cpr., 1873, preoc), Beanella Dall 

 (Beania Cpr. non Johnstone), Arthuria Cpr., Aulacochiton (Shut- 

 tleworth restr.) Cpr., Fremblya H. Adams (= Streptochiton 

 Cpr., MS.), Euplaciphora (Shuttleworth restr.) Cpr., Guildingia 

 Cpr., Macandrellus Cpr., Stectoplax Cpr., Choneplax Cpr., Chi- 

 toniscus Cpr. (non Herrmanssen). It is believed that the publi- 

 cation of these tables will be beneficial in several ways, as in 

 giving a general view of Dr. Carpenter's classification, and espe- 

 cially in calling attention to the characters which it is desirable 

 should be distinctly noted by those who may describe new spe- 

 cies of Chitonidae, for the want of which it is impracticable in the 

 majority of cases, to properly classify by determining the genus 

 or even to subsequently recognize the species. The publication 

 of the entire monograph only awaits the preparation of the illus- 

 trations (already drawn) which have been delayed by circum- 

 stances entirely beyond the writer's control. 



" The Cephalopods of the northeastern coast of America." Part 

 n. " The smaller Cephalopods (etc.), " by A. E. Verrill (Trans. 

 Conn. Acad. Sci., v., pp. 259-446, pi. xxvi-lvi, June, 1880, Dec, 

 1 881). Part 1 of this important work was noticed in this record 

 for 1880. The second part is now completed, forming full mate- 

 rial for a manual of the subject, which it is understood will be 

 issued in the form of a " Report on the Cephalopods," in connec- 

 tion with the "U. S. Fish Commission Report for 1879," which 

 appears early in 1882. 1 The first two sheets, which appeared in 

 1880, contain references to additional specimens of Architeuthis 

 harvejn, and a full description of Ommastrephes illecebrosus (Les- 

 ueur) Verrill. The new names applied in the subsequent por- 

 tion of the paper are Cheloteuthis for C. rapax n. s. (by typo- 

 graphical error Chiloteuthis) from a somewhat imperfect speci- 

 men which is subsequently referred to as a synonym of Lcstotcu- 

 this fabricii (Stp.) Verrill {Sepia Icligo Fabr. Fauna Gronl.); Des- 

 moteuthidae V. fam. nov. containing Desmoteuthis n. g. erected 

 upon LeacJtia Jiypcrborea Stp. ; two new varieties (boreal is and 

 pallida) of Loligo pealei Lesueur; Stoloteuthis n. g. for Sepiola 

 leucoptera V. ; Rossia megaptera V. n. s. from near Newfoundland ; 

 and Alloposidae V. fam. nov. for Alloposus V. (1880). An appen- 

 dix follows, with descriptions of additional material and a crit-
