Cranocephalus Goësi. 95 



The genus Cranocephalus is well defined from all the other 

 genera of the family. In the short head and in the second pair of antennae 

 being concealed under the head and the perœon it resembles SiinorJiynchotus 

 and Tullbergella; in the form of the pergeopoda it comes tolerably near 

 to Stebbingella^ which also has broadly expanded femora in the last three 

 pairs. Only one species is hitherto known. 



1- Cranocephalus Goësi, n. sp. 



The name is given in honour of D:r Axel Goes of Kisa, Sweden. 

 Pi. IV, fig. 7—9; and p. 21, fig. 5; p. 32, fig. 53; and p. 38, fig. 72. 



Diagn. The body is smooth and even, with a thin but hard integument. 



The head is nearly as long as the first six perœonal segments 

 together; the hind part is a little constricted; the broadly 

 triangular rostrum is scarcely half as long as the rest of 

 the head. 



The under margin of the carpus of the first pair oi perceopoda 

 is entirely smooth, with the hind corner projecting into a short 

 sharp tooth; the hind margin is strongly serrated, without 

 spines or bristles, the hind margin of the metacarpus is as 

 long as the free under margin of the carpus, and forms an 

 edge which is smooth on the hind margin but armed with 

 a few sharp teeth on the under margin. The under margin 

 of the carpus of the second pair is smooth, with the apical 

 tooth somewhat longer than in the first pair; the hind 

 margin is feebly serrated, and providod with some very 

 short bristles; the hind margin of the metacarpus is about 

 as long as the free under margin of the carpus, the upper 

 part is smooth; the lower obliquely truncated end is provid- 

 ded with a few strong teeth. The femur of the sixth pair 

 is a fifth part longer than broad, with the lower hind corner 

 produced downwards into a broadly rounded process, which 

 reaches to the apex of the genu. The seventh pair reach 

 to the apex of the carpus of the sixth pair. 



The lateral parts of the i^l^onal segments are a little produced 

 behind, and sharp-pointed. 



The peduncle of the first and second pairs of uropoda is 

 fully twice as long as the inner ramus.
