Packard's article on the marine invertebrates found at Caribou Island, Straits of BeUe Isle, which 

 was published in the Canadian Naturalist and Geologist for December 1863, is, he says, 

 embodied in the present article, with typographical corrections. " Valuable information 

 regarding the identification of several species of Amphipoda has been kindly communicated 

 through Dr. Liitken by Mr. A. Boeck." The Amphipoda occupy pages 297-301. 



" Monoculodes nuhitaltis nov. sp. [PI. VIII., fig., 4.]," is thus described : — ' Female. Cephalic 

 ring produced into an obtuse, tumid rostrum, smaller than in M. carinatus Bate, of 

 the British shores ; the segments of the thorax and abdomen are not carinated above as in 

 that species, being nearly smooth, while the abdominal segments are slightly sinuated just 

 behind each suture. Eyes small, round, situated just above and opposite the insertion of 

 the superior antennfe ; not colored in the adult, but black in the young. Superior antennfe 

 a little longer than the peduncle of the inferior pair ; inferior antennae reaching to the hind 

 edge of the fourth thoracic, including the cephalic, ring ; the penultimate and last joint of 

 the peduncle equal in length ; flagellum about half the length of the whole antenna. Both 

 pairs of gnathopoda very equal in size, the propodos being long, ovate ; anterior pair 

 slenderer than in M. carinatus, palm very oblique, with minute hairs ; dactylos two thirds 

 the length of the propodos; carpos minute, not prominently produced as in M. carinatus, but 

 rather continuous with the propodos. The second pair are much stouter and more ovate than 

 in M. carinatus, according in this respect more with that of M. demissus, Stimps. In form it 

 closely repeats that of the anterior pair ; carpus with a long, slender, spine-like prolongation 

 from the palm, forming a thumb closely appressed to the propodos, but not extending to the 

 middle. Palm of the propodos on the anterior half fringed with hairs. Dactylos one-half 

 as long as the propodos. Anterior pair of thoracic legs subequal ; posterior pair of thoracic 

 legs twice as long and much larger than the anterior, coxse regularly short, pyriform. 

 Abdominal legs large, equal in size, reaching nearly to the tip of the caudal stylets, which 

 are lanceolate, very slender, acute j the first pair being a very little longer than the third. 

 Color pale, mottled with slate. Length, -50 inch. 



" It differs from M. demissus of Grand Menan, in its color, and the very unequal antennas. 

 From M. carinatus of the British Isles it may be readily distinguished by the very equal 

 gnathopoda and non-carinated segments, the slenderer antennae, and the smaller, round eyes.

In this masterpiece Professor Sars has taken the opportunity to describe, with great fulness of 

 detail and a clearness that leaves nothing to be desired, the whole structure of an Amphipod, 

 illustrating the description by figiues which are not only elaborate and artistic but possess the 

 further virtues of being in the most satisfactory manner explanatory and intelligible. In the 

 period of active investigation since this work was published, one or two of its statements
