46. Loligo Brevipinna.—" Sac short, thick, cylindric anteriorly ; sub- 

 compressed, obtuse, and rounded posteriorly ; fins narrow, rounded, 

 distant." This species has been described and figured by M. C. A. 

 Lesueur. Journ. Acad. Phil. iii. 282. Tab. 10. It was taken in Dela- 

 ware Bay. It makes a nearer approach to the L. Sepiola, in the form of 

 the body and the position of the fins, than to any of the other species. 

 The acute author of this description states, in opposition to Blainville, 

 that the sepiola occurs in the British Channel, he having caught one in 

 the Port of Havre in 1814. Pennant's specimen was taken off Flintshire, 

 and there is one, now before us, from the Frith of Forth. (F.) 



47. Lernaea. — M. Lesueur lias published in Journ. Acad. Phil. iii. 286. 

 descriptions and figures of three new species belonging to this Linna?an 

 genus. Two of these, cruciata and radiata, may be included in the ge- 

 nus Lerneocera of Blainville, provided this genus were modified to in- 

 clude, in a section, species with simple arms. If those with simple arms 

 be excluded, our author proposes a new genus for their reception, viz. 

 Lernecenicus, " body elongated, attenuated before, and dilated behind ; 

 head furnished with many simple subcorneous arms radiating around the 

 mouth." The third species belongs to the genus Lerneopenna of Blain- 

 ville, and is termed L. Blainvillii. (F.) 



48. Batrachoides. — This genus was instituted by Lacepede, and is repre- 

 sented by the Gadus Tau of Bloch. Ich. Tab. 67. f. 2. M. Lesueur haa 

 recently added two species ; viz. B. Variegata from Egg harbour, New 

 Jersey, and B. Diemensis, from the coast of Van Diemen's Land. Journ. 

 Acad. Phil. iii. 395. Both these species belonged to the section having 

 cirri. This group of fishes seems nearly connected with the Lophius 

 of Linnaeus, from which, however, it differs in the greater hardness of 

 the skeleton, and in the pectorals being destitute of those footstalks, re- 

 presenting the radius and ulna. (F.) 



49. Sword-fish. — A specimen of the Ziphias gladius was found on a 

 6and-bank in the Tay, in the end of August, and sent to Dr. Fleming 

 of Flisk. It was upwards of six feet in length, exclusive of (he snout or 

 sword, which was two feet and a half. It had been long dead, and was 

 much mutilated, and putrid. On the bronchia; one specimen of the Tris~ 

 toma Coccineum of Cuvier occurred. The stomach contained numerous 

 remains of the Loligo sagiitata, which seems its ordinary food, along 

 with the following intestinal inmates, Ascarus incurna, Tetrarhynchus at* 

 (cnufitus, and Bothriocephalus plicutuf, of Budolphi. (F.)

50. Natural Ice-houses near Salisbury, North America. — Chasms of con- 

 siderable extent are met with in the inica slate, (Lat. about 13° N.) form- 

 ing natural icehouses, where the ice and snow remain most of the year. 

 One of tlicsc, in the cast part of the town, is perhaps worthy of a particular
