166 S. II. SCUDDER ON SPINED MYRIAPODS 



the spines, which are less than half as long as the width of the body. Prom the character 

 of the spines, however, the surface character and general appearance of the segments, and 

 the size of the body, it can hardly be doubted that it belongs to this species. No legs are 

 present, but there are two features worthy of note : first, on one side of the fourth seg- 

 ment behind the head protrudes a pair of straight, attingent, tapering, bluntly-tipped, so 

 far as can be seenunjointed rods, directed at right angles to the body and inclined a little 

 forward, half as long as the width of the fourth segment, and each considerably stouter 

 than the spines; they certainly may be legs though they differ somewhat from them; but 

 appearing at this place only and recalling similar organs in other specimens of Euphoheria 

 one cannot help inclining to believe them to represent intromittent organs, and this speci 

 men has then a special interest from being the only one yet found in which a pair is pre- 

 served ; second, the appendages of the head ; the head is considerably broader than the 

 body, scarcely longer than the body segments, broadly and very regularly rounded in 

 front ; from either side of the front, about midway between the middle and the outer mar- 

 gin, springs an antenna, composed of four joints : the first, of which only the apical part 

 can be seen and that obscurely, seems to be small and cylindrical ; the second, also obscure, 

 is large, stout, cylindrical, perhaps enlarging apically, a little longer than broad, termina- 

 ting bluntly ; the third about as long as the second but very much slenderer, cylinl 

 drical, enlarging a little apically, terminating bluntly and followed by an ovate termina 

 joint, twice as long as broad and a little narrower than the apex of the penultimate joint. 

 The length of the fragment is 54 mm. ; probably not more than half of the whole is pre- 

 served ; its greatest breadth is 7.5 mm. and just behind the head 6 mm. ; the head is 

 9.5 mm. broad and 3 mm. long; the whole antenna 3.3 mm. long; second joint 1 mm.; 

 third joint 0.9 mm. ; fourth joint 0.45 mm. ; greatest width of second joint 0.5 mm. ; third 

 joint 0.55 mm. ; fourth joint 0.38 mm. 



Another specimen and part of its reverse sent by Mr. Carr represent the larger part of 

 a curved body on a lateral view with a few spines and many legs, none of it very well 

 preserved ; the head is not reached anteriorly although very few segments behind the 

 head can be missing. Nearly thirty segments are present, representing a large animal, 115 • 

 mm. long so far as preserved. The only parts worthy of special mention are the legs, 

 which are in some places very well preserved ; they are very nearly as long as the width 

 of the body ; the first and second segments are of equal width with parallel sides, but 

 beyond this the leg tapers to a point; the second joint is much longer than the others, 

 longer indeed than the third, fourth and fifth together ; the first and third are of equal 

 length and a little longer than the fourth, fifth and sixth, which are of similar length ; the 

 first joint is nearly twice as long as broad, the second nearly six times as long as broad, 

 the third twice as long as broad. The legs therefore essentially resemble those of Acan- 

 therpestes major, differing from them only in detail; the specimen figured (PI. 13, fig. 10) 

 shows no sign of any median carina, which is visible on some of the legs and not on others. 

 The leg measures 7.25 mm. in total length, the first joint being 1.4 mm. long, the second 

 2.75 mm., the third 1.3 mm., the fourth and fifth each 0.9 mm. ; the last 1 mm. ; the width 

 of the second joint is scarcely more than 0.5 mm. 



The specimen received from Mr. Armstrong is very imperfect and adds nothing to our 

 knowledge of the species. It is a nearly entire body of a small animal preserved on a side
