 for the reception of a single species, H. diplochelatus ; the namee of the other new spe- 

 cies are Vihilia serrata and F. hodgsoni. Saunders.

Expedition, conducted by W, A. Cunnington, 1904—1905. Report 



on the Branchiura. In: Proc. Zool. Soc. London, S. 262 — 282, 3 Taf., 1913. 



The Branchiura of Lake Tanganyika are, like the other inhabitants, notice- 



able for the fact that the great majority of them are to be found only in this 



lake. Nine species were taken, of which seven were found to be peculiar to 



Lake Tanganyika and are here described as new species, two, Argulus africanus 



Thiele and Dolops ranarum Stuhlmann, occurred in other African Lakes as well. 



It is interesting to note that the Tanganyika endemic species do not necessarily 



infest endemic fish, although 101 out of 115 species of fish living in this lake 



are endemic. Thus the host of Dolops ranarum was found to be an endemic fish 



and, vice versa, an endLemvo, Argulus was found living on a widely distributed fish. 



The author gives a diagnostic table for distinguishing the species of African 



Argulidae. His new species are described under the names of Argulus incisus, 



A. ruhropunctatus, A.personatus, A. exiguus, A. angusticeps, A. striatus and A.rnbescens.

 of the Crustacean Family Sergestidae. In: Journ. Linn. Soc, Vol. XXXII, 

 S. 219—223, 1 Taf., 1913. 



The genus Aphareus Paulson has had to be renamed Aphaeoearis owing to the 

 previous name being already occupied by a genus of fishes. Aphaeoearis elegans is new 

 species belouging to this genus and ia here described by the author. It was found in a 

 small collection of Crustacea from Thursday Island, Torres Straits. Saunders.

 In: Journ. Linn. Soc, Vol. XXXII, S. 225—230, 1 Textfig., 1913. 



Before the larvae of Palinurus lalanclii become phyllosomas they pass through 

 a Nauplioid stage lasting for 4 — 6 hours after the time of hatching. The presence 

 of this peculiar stage in the life history of the South Africa crawfish is suggested 

 by the author as the reason for the abendance of Palinurus in S. African and its 

 scarcity in European waters. The naupliosoma has very long antennae which 

 help it to swim upwards towards the surface w^aters when food is plentiful for 

 the young larvae. Phyllosoma is more adapted for horizontal progression and is 

 less capable of making its way upward. The appearance of the naupliosoma is 

 shown in a figure. Saunders.

TliaumastocJieles japonicus is the name given by Ca Im an to his new species. 

 It has previously been confused with T. zaleucus Willemoes-Suhn and the author 

 therefore gives a careful description of the characteristics of the two species. 

 One of the chief points of difference is in the arrangement of the teeth on the 

 finger of the large cheliped. This difference is shown by a figure in the text.
