H. Richardson — Isopods of the Bermudas. 303 



Island Cave, collected by A. E. Verrill, 1901. Also Europe, North 

 America, South America, North Africa, Sumatra, Madagascar. 



Leptotrichus granulatus Richardson, sp. nov. 



Plate XL. Figure 58. 



Body roughly and minutely granulated. Color light reddish or 

 yellowish brown, with markings of dark brown in patches on each 

 segment, forming four longitudinal rows, the two median rows not 

 extending anteriorly beyond the third segment of the thorax in one 

 specimen, and in the other being almost obsolete. 



The head is produced in front in a prominent rounded median lobe, 

 and at the sides in. large rounded lateral lobes. The eyes are small, 

 but distinct, and are placed at the base of the lateral lobes. The ex- 

 ternal antennae are very short, not reaching the anterior angle of the 

 first thoracic segment. The fourth joint of the peduncle is not 

 longer than the third ; the flagellum is composed of two joints, the 

 first of which is about half the length of the second. 



The thoracic segments are subequal in length, the lateral parts 

 broadly expanded. 



The first two abdominal segments have the lateral parts undevel- 

 oped. The third, fourth and fifth segments are broadly expanded 

 laterally, the outer margins forming a continuous and unbroken line 

 with the margins of the thoracic segments. The terminal segment 

 of the abdomen extends but a distance of half its length beyond the 

 epimera of the preceding segment ; its surface is smooth. The basal 

 joint of the uropoda attains half the length of the terminal segment. 

 The inner branch reaches the apex of the last segment. The outer 

 branch extends half its length beyond this. 



Two specimens were collected by A. E. Verrill and party at the 

 Bermudas in 1898. They were found in dead coral at Castle Harbor. 



Type in Peabody Museum, Yale University. Cat. No. 3333. 



This species cannot be identified with any of the described species 

 of the genus: L.panzerii (Audouin and Savigny), L. tauricus Budde- 

 Lund, L. squamatus Budde-Lund, and i.* lentus (Budde-Lund), 

 although it seems more closely related to the last named than to any 

 of the former.
