12 G. O. Sårs. 



3. Apiis ScuUeyi, G. O. Sårs, n. sjj. 



(Pl. I, figs. 9—13), 



Specific Characters. — Ç Body rather slender, with 

 the exposed part much produced. Carapace less depressed 

 than in the preceding species, and of a rather different shape, 

 being oval in outline, with the front broadly rounded, and 

 the lateral contours but very slightly arched, terminal lobes 

 less appressed, posterior sinus rather broad and evenly 

 rounded at the bottom, with the marginal denticles small, 

 but distinct. Eyes, post-ocular tubercle, cervical sulcus and 

 dorsal keel about as in the preceding species, shell-glands, 

 however, far less conspicuous. Surface of carapace minutely 

 scabrous from numerous small prickles, especially densely 

 crowded together in the posterior part. Exposed part of 

 body exceeding the median length of the carapace by nearly 

 its 3rd part, and comprising about 30 segments, of which the 

 14 posterior ones are without ventral appendages. Caudal 

 filaments well-developed, exceeding half the length of the 

 body. Length (not including the caudal filaments) 26 mm. 



Remarks. — Though having the same number of caudal 

 segments as the preceding species, together with which it 

 was found, this form cannot properly, in my opinion, be 

 combined with it, because the carapace is very different both 

 as to form and sculpture. I have therefore found it necessary 

 to establish for its reception a new species, which is named 

 in honour of the gentleman by whom it was found, Mr. W. 

 ScuUey. Unfortunately only a solitary, but well preserved 

 female specimen has come under my notice.
