ZOOLOGICAL LITERATUKE. 
pendages very long and narrow, linear. In this genus there are two species, 
namely Hyalophtjllum pdlucidum and H. vitreum. 
Prof. Hiickel considers that this genus might advantageously 
be divided into two, or at least two subgenera. 
The first he calls Pyromma, which consists of Sapphirina in its restricted 
sense. Its cliaracter is as follows : — Eyes either red, yellowish red, or brown. 
The anterior pair of eyes situated some way within the anterior margin. The 
two last joints of the posteiior antennae together shorter than the second. 
Inner branch of the fourth pair of feet well developed and as large as on the 
other feet.” In this subgenus there are three species : Sapphirina gegenhaurij 
S. edivardsii, and S. clausii. The second subgenus he names Cyanomma, or else 
a second genus Sap ihiridina j in this there is but one species, namely Sap- 
pkirina darwinii (^Sapphiridina danuinii). 
CALIGIDiE. 
Prof. Dr. 0.. Claus (Zeitschr. ftir wiss. Zool. p. 305) contributes to our 
knowledge of the parasitic Crustacea (Beitrage zur Kenntniss der Schmarot- 
zerkrebse) in a paper on the organization ol Caligus branchialis, Malm {gra- 
cilisy Van Ben;), and pectoj'alis, MlilL, which he obtained at Heligoland, as 
well as others which he took at Nice and Messina. He chiefly treats of the 
nervous and circulatory systems, and supports the opinion of Pickeiing and 
Dana of an anterior and posterior valvular apparatus, but doubts the existence 
of a central pulsating heart, which Siebold states has been overlooked by the 
former. 
Pandaridas. 
Liitkenia, g. n., Claus, Zeitschr. wiss. Zool. 1864, p. 369 : Cephalopereione 
diviso, annulis pereionis secundi et tertii pans inter se coalitis ; foliis dorsa- 
libus ammli pereionis quarti duobus mediocribus ; annulo genitali lato, postice 
profunde inciso ; cauda baud articulata, obtecta ; foliolis caudalibus mollibus, 
setis brevissimis ; pedis primi parts ramis biarticulatis, ramo interno parvulo 
setis carente, externo in modo maxillipeduin valde elongato, setis phimosis 
nullis ; secundi et tertii parts ramis biarticulis, setis phimosis inslructis j quarti 
parts ramis foliaceis, baud articulatis, setis phimosis destitutis (fila ovigera 
longissima).— aslerodermi, sp. n. Size of the female 10-11 mm. The 
male was found also. From the gills of Asterodermus coryphcenoides (Messina). 
Notodelphidas. 
Prof. Claus (Zeitschr. wiss. Zool. 1864, p. 373) treats on Eutomostraca 
dwelling within the cavity of Tunicata, and describes three species of Bomo- 
lochus : viz. Bomulochus soletc 2 , Bomolochus corntdus $ , and a third form, 
which he considers to be sufficiently distinct to form a new genus, under the 
name of PucanthuSy the species being Pa. halistce. He then descrtbes a new 
species under the name of Sphcsronotiis thorelli. He found the specimen in 
an Ascidian at Naples j but upon comparing it with fig. 1. pi. 2 which Costa 
published in his Catalogue, he thinks that it undoubtedly belongs to the same 
genus to which that author has given the name Notopterophorus, but with- 
out any description. It is about 4-6 mm. in length j it is nearly allied to the 
genus Dorojiygus, but iliflers from it in the form of the second, third, and 
fourth pairs of legs, which are formed of three joints and without hairs.
