340 GENERAL SUMMARY TO 



locality from whence Capt. Dixon procured his smaller shell. The largest Tertiary 

 specimen of a Brachiopod, Terebratula jjrandis, measures 4^ inches in length by 3 inches 

 2 lines in breadth, and 2 inches 2 lines in depth. It is remarkable that the largest 

 Tertiary species should be a Terebratula with a short loop, and the largest recent form 

 a Waldhehnia with a long loop. 



I here append a list of the recent species known to me, and which I published at page 

 11 of my 'Report on the Brachiopoda' dredged by Her Majesty's Ship "Challenger." 

 (An asterisk has been placed before the names of those so-called species which require 

 further investigation.)

globe, few bave been discovered recent or fresh from the sea. Only one of this sort was before known in 

 Europe, wbich was brought over by my late worthy commander, the much regretted Captain Cook, in his first 

 voyage round the world. It was in the Portland Museum, and was named by the late celebrated Dr. Solander, 

 in his MS. description of the shells of that splendid cabinet, Anontia venosa, which specimen is now in the 

 collection of Mr. Calonne, of London. This kind (as do all that are properly of this genus) adheres to 

 coral rocks by a ligament that comes from the animal through the hole in the larger valve. The internal 

 structure (peculiar to the shells of this genus) is very singular, and consists of two testaceous rays, which 

 commence near the hinge in the lesser valve, where they adhere, from whence leaving the shell they 

 proceed to near the edge, then bend towards the outer valve, and turn back to their commencement, 

 where they unite. This internal part is very delicate, and breaks upon the smallest touch, but is thicker 

 in the part nearest to the larger valve. The shell takes its name from certain parts of the animal, which 

 run in a branched form along the inside of the shell, which being held to a strong liglit, or a candle, 

 gives it a beautiful veined appearance. The outside is smooth, and of a pale brown colour." I repro- 

 duce this description, as the book seems little known, but remarkable for the period at which it was 

 written. 



1 This remarkable deep-sea species bears much resemblance to the Jurassic T. nucleata of Schlotheim, 

 and their loops are identical. 



2 Terebratulina Wyvillei is the largest recent or fossil species of the genus with which I am 

 acquainted. It measures 2\ inches in length, 2 in breadth, and 1 inch 4 lines in breadth. Terebratulina 

 Crossii is the second largest form, measuring 2 inches 1 line in length, by If inch in breadth, and 1 inch 

 in depth.
