latus and S. sculptus (U. S. Nat, Mus., coll. Dr. T. H. Bean) ; 

 Hlppolyte acuminatus (coll. Goode) ; and Domecia hispida (coll. 

 Yale Exp., 1898). To these should be added Hlppolyte bidentata 

 Bate, making the total number of species 87, now known.* 



Two new species of Pycnogonida, the only ones known in the 

 region, are described and figured. 



In the paper on the marine Mollusca a large number of species 

 (about 80) are added to the fauna, and most of them are figured. 

 Of these 25 species are described as new. This makes the total 

 number about 350. In the article on Nudibranchs, etc., nine new 

 species are described, including a very large ApLysia and a new 

 genus (Pleurobranchopsis), allied to Pleurobranchus, but without 

 a shell. In the three papers on echinoderms about 40 species are 

 recorded, including numerous additions to the fauna, but no new 

 species, except Synapta aca?ithia, described by Prof. Clark (1899, 

 p. 134). Of Tunicata four new species are described, including a 

 large and elegantly colored Diazona (D. picta), and three others 

 are added to the fauna. The compound ascidians, which are 

 numerous, have not been worked up. A small reddish brachio- 

 pod ( Cistella cistellula) was found attached to the under side of 

 corals in Harrington Sound. It agrees closely with specimens 

 from Naples. Several Bryozoa are recorded for the first time, 

 and two remarkable new species are described. f One of* these 

 ( Caiilibiigula armata) is the type of a new genus, allied to Bugida, 

 but it has an articulated stem ; the other (Barentsia limida) is 

 allied to Pedicellina. 



In the ninth paper, two new planarians and two newnemerteans 

 are described, and a previously known species of each group is 

 recorded, both of which are found at Naples. These orders are 

 sparsely represented at Bermuda and none had been recorded 

 previously except the terrestrial Tetrastemma agricola. Of 

 Gephyrcea 4 species are recorded, two of which (Aspidosiphon 

 spinulosum and GoJfingia elongata) are new. Of Annelida 60 

 new species are described and at least 10 others are added to the 

 fauna, which about trebles the known species. About 25 of the 

 new species are Syllida3. Several new genera are described and 



to form irregular transverse bands. There are four bands on each of the pro- 

 podal and terminal joints of the second and third pairs of legs; chelae and eye- 

 stalks spotted with red." (M. J. Eathbun.) 



Total length about 40 mm . It becomes much larger.

* The marine Isopoda have been worked out by Miss Richardson, who enu- 

 merates 23 species. About 25 species of Amphipoda were also collected by the 

 Yale party. An undetermined fresh-water ostracode crustacean was found 

 abundantly in a rain-water cistern at Eailey Bay. , 



\ Another remarkable new bryozoan often occurs at Bermuda : 



Amathia Goodei Y., sp. nov This forms large, intricately branched clusters. 

 4 or 5 inches high and broad, with the branches thick, soft, and flaccid, and more 

 or less anastomosing, often 2 to 3 mm in diameter. The zooids are numerous, 

 arranged in large, dense, elongated clusters, composed of several close^ rows, 

 which often nearly or quite surround the stem, and extend for some distance 

 below the nodes, but are scarcely at all spiral (coll. of G. Browne Goode).
