Plate LXX. Figure 5. 



Three specimens of this large and handsome species were obtained. 

 We found it difficult to preserve well by any of the ordinary 

 methods, either in alcohol or formalin. It is soft, thin, and very 

 mutable in form. 



Its color, in life, is a very rich, dark, purplish black or very dark 

 maroon, with a velvety appearance, bordered all around with a nar- 

 row marginal band of bright orange, edged with light orange, 

 while the extreme edge is purplish brown ; under side brownish 

 purple. 



Length, in life, 50 to 60'"°' ; breadth, 25 to 30™'°. 



Under stones at and just below low-tide, usually associated with a 

 dark botrylloid compound ascidian or with a dark purplish sponge, 

 with both of which it corresponds closely in color. 



This is one of the few species of Bermudian marine invertebrates 

 which appear to be certainly identical with Mediten-anean species, 

 though many are closely related. Among tlie nemerteans there is 

 another case of this same kind [Tceniosoma curium Hubr.), 



Pseudoceros pardalis, sp. nov. 



Plate LXX. Figures 6, 6a. 



A large, broad species, covered with yellow spots. 



Body, as preserved, broadly elliptical or oblong-ovate, subtruncate 

 anteriorly, with thin undulated margins. Ocelli numerous. 



Color, in alcohol, brownish black, covered with numerous round, 

 pale yellow spots (probably bright yellow in life). Length, 60""" ; 

 breadth, 40"'". 



The only specimen of this fine species was collected many years 

 ago by Dr. C. Hartt Merriam and presented by him to the Museum 

 of Yale University. 



NEMERTINA. 

 The most interesting nemertean, as well as the most common, 

 appears to be identical with a Mediterranean species of wide dis- 

 tribution. Mr. W. R. Coe, who has studied the Naples nemerteans 

 in the Biological Station, made sections of my Bermudian specimens 

 for comparison, lie has given me the following synonymy and 

 memoranda concerning this species: —
