REPORT ON THE AMPHIPODA. 233 



irregularmeute triangulifornie, y su augulo anterior, que es el mas largo, sostiene le cabeza : 

 en el posterior esta inserto el segmento siguiente ; las patas ocupan el angulo inferior, que 

 tieue ademas dos vejiguillas branquiales adaptadas d la base de las patas; los dos segmentos 

 que sigueu son, coiuo el resto del cuerpo, subcilindricos, llevando cada uno dos vejiguillas 

 branquiales ; las patas del primero de los tres ultimos pares son muy cortas y rudimentarias, 

 y las de los otros dos prolougadas y subquiliformos, con el penilltimo articulo dentellado en 

 el lado interne; dos filetes espiniformes por bajo del abddmen. — Color moreno amarillento 

 claro. — Longitud, S lin." 



Caprella brevicoUis, n. s., pi. i. fig. 4, is defined : — 



" C. fusca ; capite brevi, subglohoso ; antennis medioerihm ; pedibus secuvdi pai-is antice ovatis, 

 suhglobosis." It was taken 'with tbe preceding form. 



Caprella spinifrotis, n. s., is thus defined : — 



" C. capite brevi, antice suhgloboso ; fronte spinoso ; antennis superioribus longis pilis ciliatis ; 

 manibus secu7ii.U ^^ari's magnis, elongatis, intus fortiter einarginatis." This species was 

 founded on a damaged specimen. 



In the " Ciamianos," the genus Cyamus is described. The name of Lamarck is attaclied to it, as 

 though he were the originator of the name. The species Cyamus gi-acilis, Roussel de 

 Vauzeme, figured on pi. 4. fig. 7, is defined with the words: — "C. cinereo-virescens ; carpore 

 elongato, subfusiformi; appendicibus bi-anquialibus elongatis, cylindraceis, simpUcibvLS, ad 

 basim bitubereulatis." 



The Atlas containing the figures referred to in these descriptions is dated 1854. 



The new species, Talitrus chilensis, Ordiestia brevicoi-nis, Orchestia gayi, Ampldtoe gayi, 

 Gammarus chilensis, Capjrella brevicollis, and Capirella spiinifrons, are not included in the 

 list of the Brit. Mus. Catal., 1862. Caprella longioollis is figured and described in that 

 work, but as Mayer has pointed out, the species is by an error assigned to Lucas, and its 

 habitat given as Algeria instead of Chili. 



For the genus Nicea see Note on Rathke, 1837. Tlie genus Lalaria is a synonym of Aora, 

 Kr0yer, 1845, and the species Lalaria longitarsis is identified by Spence Bate with 

 Kr0yer's Aora typica. Caprella brevicollis is considered by Mayer to include the female and 

 young forms of Caprella longicollis, and, as Caprellina longicollis, the species becomes the 

 type of a new genus founded by G. M. Thomson in 1879. This genus I propose to name 

 Caprelliiwpsis, since Caprellina is preoccupied as tlie name of the group to which the genus 

 belongs. Caprella spinifrons is left indeterminate by Mayer.

Schi0dte comments first on the slow growth of knowledge in regard to the subterranean fauna. 

 In his historical review he mentions Tellkampf's Triura cavernicola, which, he says, " seems 

 to belong to tlie order of Amphipoda," an obvious error in which he is followed by Boeck. 

 At page 2G, he institutes the new genus Niphargus, with this definition : —
