CRUSTACEA MALACOSTRACA. 



Distribution. It is remarkable that this species is not known from the Faeroes, the Shet- 

 lands or the Hebrides. It occurs at Scotland, England and Ireland (Bell), on the Belgian coast 

 (v. Beneden), at Concarneau (Bonnier) and in the Gulf of Gascogne, 136 fm. (Caullery); in the Mediter- 

 ranean it is known from several points along the Italian west coast and in the Adriatic. It is met 

 with in the Skager Rak, northern Kattegat and a considerable distance down into the Sound (Meinert); 

 it is found at Bohuslan (Goes) and along the whole west coast of Norway (M. Sars). Finally its occur- 

 rence in Varanger Fjord and in the western part of the Murman Sea has been stated by Birula, but 

 Appellof doubts that the species has been taken east of North Cape. 



Spongicoloides n. gen. 1 



Body smooth, with exception of about half of the carapace which is adorned with a number 

 of small spines. Rostrum short, compressed. Telson has the posterior end broad and flatly rounded; 

 it is a little longer than the uropods, and with two longitudinal rows of teeth on the upper surface. 

 The exopod of the uropods has no transverse fissure. 



Eye-stalks short; eyes of moderate size, with whitish pigment. The antennular peduncle short; 

 its basal point not concave dorsally. The antennal squama of considerable size, with its distal end 

 broadly rounded inside the marginal spine. 



First maxillipeds have the exopod well developed; second and third maxillipeds completely 

 without exopod. The three anterior pairs of trunk-legs increase in length in posterior succession so 

 much that the third pair are nearly twice as long as the first. Third pair have the carpus oblong, 

 not triangular, the chela long, very slender, formed essentially as in the two preceding pairs. 

 Fourth aud fifth pairs of legs have their distal joints undivided; seventh joint terminates in a claw 

 and behind this a somewhat smaller claw-shaped spine is seen. 



The abdominal appendages behind the first are biramous. 



Eggs very large. 



The branchial formula is as follows:

1 The descriptions of the genus and the species are written tolerably in accordance with those given by Prof. A. Al- 

 cock of forms of the same family in his valuable work: A descriptive Catalogue of the Indian Deep-Sea Crustacea Decapoda 

 and Anornala, in the Indian Museum. 1901.
